Western culture has tended to divide musical practices into two very broad fields, the vernacular and the cultivated. Vernacular refers to everyday, informal musical practices located outside the official arena of high culture—the conservatory, the concert hall, and the high church. The field of vernacular music is often further subdivided into the domains of folk music (orally transmitted and community based) and popular music (mediated for a mass audience). Cultivated music, often referred to as classical or art music, is associated with formal training and written composition. The boundaries between so-called folk, popular, and classical music are becoming increasingly blurred as we enter into the 21st century, due to the pervasive effects of mass media that have made music of all American ethnic/racial groups, classes, and regions available to everyone.
Historians and musicologists now agree that America’s most distinctive musical expressions are found, or have roots in, its vernacular music. Early immigrants from Western Europe and the slaves stolen from Africa brought with them rich traditions of oral folk music that mixed and mingled throughout the 18th and 19th centuries to develop uniquely American ballads, instrumental dance music, and spirituals. By the early 20th century, the folk blues emerged and would go on to form the foundation of much of our popular music. Beginning with 19th century minstrel and parlor song collections, and threading through the 20th century recordings of Tin Pan Alley song, gospel, rhythm and blues, country, rock, soul, and rap, the print and electronic media fueled the growth of American popular musical styles that today have proliferated across the globe. Jazz, sometimes considered America’s “classical” music, certainly had roots in early 20th century folk and popular styles (see Chapter 7: Jazz). And many of America’s best-known classical composers including George Gershwin, Aaron Copland, Virgil Thomson, and Duke Ellington based their extended compositions on vernacular folk and popular themes (see Chapter 5: European and American Art Music since 1900).
Folk music was once thought of as being simple, old, anonymously composed music played by poor, rural, nonliterate people representing the lower strata of our society (mountain hillbillies, southern black sharecroppers, cowboys, etc.). Today scholars have expanded the field by defining folk music as orally transmitted songs and instrumental expressions that are passed on in community settings and generally show a degree of stability over time. Rather than viewing folk expressions as vanishing antiquities, this perspective suggests folk music can be a dynamic process that continues to flourish within many communities of our modern society. Using this model popular music may be defined as mass-mediated expression that changes rapidly over time, and classical/art music as musical practices centered in formal training and written composition.
In the late 19th and early 20th centuries, American folk music collectors wrote down the words and melodies to a variety of traditional expressions including Native American ritual songs, African American spirituals and work songs, Anglo American ballads and fiddle tunes, and western cowboy songs. Later they broadened their interest to include the traditional expressions of ethnic and immigrant communities such as the practices of Hispanic, Irish, Jewish, Caribbean, and Chinese Americans, most of whom lived in urban areas. With the advent of portable recording technology in the 1930s, folklorists like Alan Lomax began the task of documenting America’s folk music and compiling the Archive of American Folk Song, which today, along with the Smithsonian Folkways Recordings, offers students the chance to hear and study authentic regional folk styles.
Most Anglo and African American folk genres are built around relatively simple (often pentatonic) melodies, duple or triple meter time signatures, and a series of harmonic structures built around the tonic, subdominant, and dominant chords. But much of the emotional appeal of folk music comes from the grain or tension of the voice. Vocal textures vary greatly, ranging from the high, tense, nasal delivery associated with white mountain singers, to the more relaxed, throaty, rough timbre of southern African American blues and spiritual singers.
In addition to studying song texts and melodies, folk music scholars have paid a great deal of attention to the social function of folk music. They seek to understand how a particular song or instrumental piece works within a specific social situation for a particular group of people. For example, how do Native American chants and African American spirituals operate within the context of a religious or worship ceremony; how are Anglo and Celtic American fiddle tunes central to Appalachian and community gatherings; how did traditional blues and ballads reflect contrasting world views of southern blacks and whites; and how do West Indian steel bands and Jewish klezmer ensembles serve as markers of cultural pride?
The self-conscious revival of folk music by middle-class urban Americans has been going on since the 1930s. During the Depression and WWII years, folk artists like Louisiana-born Huddie “Lead Belly” Ledbetter and Oklahoma-born Woody Guthrie introduced city audiences to rural folk music, and along with left-leaning topical folk singers like Pete Seeger, they helped spawn the great folk revival of the post–World War II years. Folk music spilled into the popular arena with artists like the Kingston Trio; Burl Ives; Peter, Paul & Mary; and Bob Dylan writing and recording hit folk songs.
Ballads are basically folk songs that tell stories through the introduction of characters in a specific situation, the building up of dramatic tension, and the resolution of that tension. Ballads were originally brought to America by British, Scottish, and Scotch-Irish immigrants, many of whom eventually settled in the mountainous regions of the American south.
The melodies of Anglo American ballads are simple, often built around archaic sounding pentatonic (five note) and hexatonic (six-tone) scales that may feature large jumps or gaps between notes. Songs are traditionally sung a cappella in a free meter style, or with simple guitar or banjo accompaniment. The voice is delivered in a high, tense, nasal style.
Ballads are most often set in four line stanzas, with the second and fourth line rhyming:
I was born in West Virginia,
among the beautiful hills.
And the memory of my childhood,
lies deep within me still.
While older British and Scottish ballads found in the American South dealt with themes of ancient kings, queens, and magical happenings in faraway places, the 18th- and 19th -century ballads that developed in America tell stories of everyday folk involved in everyday life events, usually set in the present or recent past. Sentimental and tragic love stories, often involving violence and death, were common. Many American ballads express strong moral sentiments, warning listeners about the consequences of irresponsible behavior:
I courted a fair maiden,
her name I will not tell
For I have now disgraced her,
and I am doomed to hell.
It was on one beautiful evening,
the stars were shining bright
And with that faithful dagger,
I did her spirit flight.
So justice overtook me,
you all can plainly see.
My soul is doomed forever,
The sentimental and tragic themes of Anglo American ballads, along with the high-pitched, “whiny” vocal style, have survived and flourished in 20th-century popular country music.
The African American Spiritual has its origins in the religious practices of 18th- and 19th -century American slaves who converted to Christianity during the great awakening revivals. The earliest spirituals were African-style ring shouts, based on simple call and response lyrics chanted against a driving rhythm produced by clapping and foot stomping. Participants would shuffle around in a ring-formation and “shout” when they felt the spirit. More complex melodies and verse/chorus structures began to evolve, reflecting the influence of European American hymn singing, and accompaniment by guitar, piano, and percussion became common. Vocal ornamentations (slides, glides, extended use of falsetto), call and response singing, and blues tonality characterized these folk spirituals. In the reconstruction period black college choirs such as the Fisk Jubilee Singers arranged folk spirituals into four-part harmony, a form that became known as the concert spiritual. A blend of African and European musical practices, the spiritual epitomizes the sycretic (blended) nature of much American folk music resulting from the mixing of Africans and Europeans in the Americas.
The texts of many spirituals are taken from Old Testament themes and stories. The slaves were particularly moved by Old Testament figures like Daniel (who was saved from the lion’s den), Jonah (who was delivered from the belly of the whale), Noah (who survived the flood), and David (who defeated the giant Goliath) who struggled and triumphed over adverse conditions. The plight of the Israelites and their escape from bondage to the promised land was an especially powerful story retold by the spirituals:
When Israel was in Egypt’s land,
O let my people go!
Oppressed so hard they could not stand,
O let my people go!
Go Down, Moses,
Away down to Egypt’s land.
And tell old Pharaoh,
To let my people go!
The spiritual’s emphasis on redemption and deliverance in this world have led historians to suggest the songs had double meaning for the slaves—they affirmed their belief in the Bible as well as their trust that a just God would deliver them from the evils of slavery. The spirituals are thus seen as expressions of religious faith and resistance to slavery.
In the 20th-century spirituals evolved into the more urban, New Testament–centered gospel songs. Following the first “great migration” of southern African Americans to urban centers like Chicago, New York, and Philadelphia in the post–Word War I years, a new genre of black American sacred songs known as gospel began to appear. Unlike the anonymous folk spirituals, gospel songs were composed and copyrighted by songwriters like Thomas Dorsey and Reverend William Herbert Brewster, and by the 1930s were being recorded by urban church singers. Some, like Mahalia Jackson, the Dixie Hummingbirds, and the Ward Singers, turned professional and reached national and international audiences through their tours and recordings. But most gospel singing remained rooted in African American church ritual, and to this day can be heard in black communities throughout the north and south.
Musically, gospel is a blending of spirituals, blues, and the song sermons of the black preacher. Gospel songs are usually organized in a 16- or 32-bar verse/chorus form, often featuring call-and-response singing between a leader and a chorus. Blues tonalities are common, and singers are known for their intensive vocal ornamentations, which include bending and slurring notes, falsetto swoops, and melismas (groups of notes or tones sung across one syllable of a word). Gospel singers often end a song with a prolonged section of improvisation that combines singing, chanting, and shouting in hopes of “bringing down the spirit.” Lyrics are most often New Testament–centered, focusing on the redeeming power of Jesus and the singer’s personal relationship with the Savior.
Although gospel lyrics are strictly religious in nature, gospel music derives much of its sound from blues and jazz. Likewise, gospel music has been a source for various secular styles, including early rock and roll, soul music, and most recently gospel rap. During the Civil Rights era the melodies of old spirituals and gospel songs were used with new lyrics expressing the need to overcome Jim Crow segregation.
Blues music was the first significant form of secular music created by African American ex-slaves in the deep South in the late 19th and early 20th centuries. Growing out of earlier black spirituals, work songs, field hollers, and dance music, the blues addressed the social experiences of the ex-slaves as they struggled to establish themselves in post–Reconstruction southern culture.
Common themes addressed in early country blues songs were conflicts in love relations, loneliness, hardship, poverty, and travel. But it would be a mistake to assume that the blues were exclusively about sorrow—blues celebrated life’s ups and downs, and often reflected a keen sense of ironic wit and a resolve to struggle on against difficult circumstances.
Most of the early recordings of country blues from the 1920s feature a solo male singer like Charlie Patton, Blind Lemon Jefferson, Blind Blake, and Son House, accompanying himself with an acoustic guitar. But blues singers also used banjos, mandolins, fiddles, and harmonicas, and often played in small ensembles that provided dance music at country juke joints. Although blues has been interpreted as a highly individualistic expression because of the solo voice and first person text, the music was often played in social settings where African Americans danced, communed, and solidified their group identity.
Early blues lyrics were built around rhymed couplets that eventually became standardized in a 12-bar (measure) format that featured an AAB structure, with a couplet being repeated twice, and answered by a second couplet:
I woke up this morning,
I was feeling sad and blue. [A]
I woke up the morning,
I was feeling sad and blue. [A]
My sweet gal she left me,
got no one to sing my troubles to. [B]
The tonality is major, most often built around a 12-bar (measure) progression of the I (tonic), IV (subdominant), and V (dominant) chords. The melodic line often features bent and slurred notes, with generous use of the flatted third and seventh tones (known as “blue” notes) of the diatonic scale. The meter is usually duple (4/4), and tempos may vary from a slow drag to a fast boogie.
While the first blues were undoubtedly rural in origin, by the 1920s blues music had made its way to the city. Urban singers like Ma Rainey and Bessie Smith recorded and popularized sophisticated, jazz-tinged arrangements of blues in the 1920s, and composers like W. C. Handy incorporated blues forms into popular orchestral pieces like “St. Louis Blues” and “Memphis Blues.” In the post–World War II years the country blues was electrified and transformed into rhythm and blues (R&B) by Chicago-based artists Muddy Waters (McKinley Morganfield), Howlin’ Wolf (Chester Burnett), and Elmore James, and Memphis bluesman B. B. King. By the mid-1950s southern white singers like Elvis Presley, Jerry Lee Lewis, and Buddy Holly were blending rhythm and blues with elements of country music to create the new pop genre of rock and roll.
Perhaps America’s most influential contribution to the world of popular music has been the development of rock and roll in the 1950s. Many streams of folk and vernacular music styles, including blues, spirituals, gospel, ballads, hillbilly music, and early jazz, contributed to the evolution of rock and roll (R&R). But it was the convergence of African American rhythm and blues and Anglo American honky-tonk (country) music that led to the emergence of a distinctive new style that would dominate the field of popular music in post–World War II America.
Honky-tonk, often referred to as the voice of the downcast, working-class southern whites, was the dominant form of country music during the 1940s and early 1950s, with Hank Williams being its most famous practitioner. The music featured the tense, nasal vocal style associated with the earlier ballad tradition, accompanied by twangy guitars and fiddles, and lyrics centered on stories of loneliness and broken love relationships. Rhythm and blues was an urbanized version of older country blues that developed in cities like Memphis and Chicago during and immediately after the Second World War. Singers like Muddy Waters, Howlin’ Wolf, and B. B. King shouted and pleaded to their audiences, backed by screaming electric guitars, amplified harmonicas, and a rhythm sections of drums, bass, and piano. The music was loud, aggressive, and sensual, with lyrics boasting of sexual conquest or lamenting failed love.
The earliest rock-and–roll recordings were made by both white and black singers in the mid-1950s. The southern white artists like Elvis Presley, Johnny Cash, Carl Perkins, Jerry Lee Lewis, and Bill Haley were dubbed rockabillies because their sounds were rooted in hillbilly and honky-tonk country styles. Their covers of black rhythm and blues songs like “Rock Around the Clock” (Haley) and “Good Rockin’ Tonight” (Presley) provided some of the first and most powerful examples of how white country and black R&B could blend to form the new style of R&R. From the other side of the racial divide came black R&B singers like Chuck Berry, Little Richard, and Fats Domino, who cut their R&B sound with smoother vocals (and in Berry’s case country-influenced guitar licks) to forge a black style of R&R that was close (and at times indistinguishable) from that of their white counterparts.
Thus, R&R was the inevitable result of an interracial musical stew that had been simmering in the southern United States for several centuries. Its appearance in the mid-1950s was no accident, because this was precisely when independent record companies like Sun (Memphis) and Chess (Chicago) and innovative radio stations like WDIA (Memphis) were beginning to bring black vernacular music to a burgeoning baby boomer audience and the nascent civil rights movements was increasing public awareness of black culture. R&R was a popular style created in the studio and marketed directly for legions of young, predominantly white consumers who, thanks to the relative affluence of the post–World War II years, were in search of new leisure activities.
Musically the earliest R&R recordings were 12-bar blues played in an up-tempo 4/4 meter. Singers, black and white, would sometimes shout and snarl, but were careful to articulate their words in a style smooth enough for their predominantly white audiences to comprehend. The music was backed by a strong, insistent rhythm that accented the second and fourth beat of each measure, creating a sound that was easy to dance to. Rock’s gyrating singers and sensual dancing led many middle-class Americans, black and white, to condemn it as an immoral and corrupting force. When Elvis Presley first appeared on the nationally broadcast TV variety show hosted by Ed Sullivan in 1956, the cameras would only show him from the waist up in order to avoid his sexy moves that had earned him the title “Elvis the Pelvis.”
The lyrics to the most successful early R&R songs centered on teenage romance and adventure, recounting high times cruising in automobiles, dancing at the hop, and falling in and out of love. The lyrics to sexually suggestive R&B songs covered by R&R singers were consciously cleaned up so the music would be less offensive to middle-class (black and white) teens and their parents. Eventually the 12-bar blues form was eclipsed by the verse/chorus structure organized in 8- or 16-bar stanzas. As in earlier American popular songs, the repeated chorus was usually based on a simple but engaging melody (often referred to as the “hook”) that was easy to sing along to.
In the 1960s groups like the Beatles and folk rock singer Bob Dylan transformed R&R by writing more sophisticated lyrics addressing the complexities of love and sexual relations, alienation in Western society, and the utopian search for a new world through drugs and counterculture activities. Both American and British rock groups of the 1960s demonstrated that popular music could provide serious social commentary that had previously been associated with the arenas of modern art and literature and the urban folksong movement. Over the past four decades R&R (often referred to as “rock” to differentiate it from the R&R of the 1950s) has evolved in many directions (art rock, heavy metal, punk, indie), often cross-pollinating with related styles like soul, funk, disco, country, reggae, and most recently hip-hop. At times rock has served as the political voice of angry and alienated youth, and at other times simply as good-time party and dance music.
Rap is poetry recited rhythmically over musical accompaniment. Rap is part of hip-hop culture, which emerged in the mid-1970s in the Bronx. Graffiti art and break-dance are the other major elements of hip-hop culture. Rap lyrics display clever use of words and rhymes, verbal dexterity, and intricate rhythmic patterning. Rap artists take on different roles and speak from perspectives ranging from comedic to political to dramatic, often narrating stories that reflect or comment on contemporary urban life. Rap artists may be soloists, or members of a rap group (or crew), and may recite in call-and-response format. Rap songs are generally in duple meter at a medium tempo (about 80 to 90 bpm). The musical accompaniment of rap is made up of one or several continuously repeated short phrases, each phrase combining relatively simple rhythmic patterns produced by acoustic and/or synthetic percussion instruments. Other sounds are often added for timbral variety, textural complexity, and melodic/harmonic interest. A bass line provided by electric bass guitar or synthesizer reinforces the meter and defines the tonal center.
Old school rap was created by DJs (disc jockeys) and one or more MCs (originally Master of Ceremonies, later Microphone Controller). DJ Kool Herc began this period, providing a portable sound system and spinning records for dances at outdoor parties and small social clubs. He noticed that b-boys and b-girls favored dancing to the “break” in a record, the short section of a song when the band drops out and the percussion continues. Using two copies of the same record on two turntables, Herc was able to make the break repeat continuously, creating the “breakbeat” that became the basic musical structure over which the MC spoke or rapped. DJs Grandmaster Flash, Jazzy Jeff, and Grand Wizard Theodore invented additional turntable techniques: “blending” different records together, scratching (manually moving the record back and forth on the turntable to create rhythmic patterns with scratchy timbres), and mixing in synthetic drum sounds and other effects. An excellent example of turntable techniques is Flash’s The Adventures of Grandmaster Flash on the Wheels of Steel (1981). DJs, most importantly Afrika Bambaataa, also promoted hip-hop culture through parties and other events spread by word of mouth and at venues throughout New York City.
At first MCs spoke over records in the Jamaican DJ traditions of toasting (calling out friends’ names) and boasting (touting the superiority of their own sound system and DJ skills). Both traditions became central elements of the assertive and competitive spirit of rap and hip-hop. Rap drew on other African-American sources for some of its important features: the improvisational verbal skills and call-and-response format of the dozens (an African-American verbal competition trading witty insults), the rhyming aphorisms of heavyweight champion Mohammed Ali (“Float like a butterfly, sting like a bee / Your hands can’t hit what your eyes can’t see”), the songs and vocal stylings of the great soul-funk artist James Brown, and The Last Poets, whose members spoke or chanted politically charged poems over drumming. The first MCs to develop extended lyrical forms by rhyming over break beats were Grandmaster Caz and DJ Hollywood. The interplay of vocal and accompaniment rhythms, rhyme schemes, and phrasing are the main elements of what is known as flow. Old school flow is more regular and less syncopated than later styles. Two-line units (couplets) rhyming at the end of the lines are common during this period, such as, “Pump it up homeboy, just don’t stop / Chef Boy-ar-dee coolin’ on the pot” (The Beastie Boys). Before rap entered into the mainstream entertainment industry, portable cassette players provided a cheap and robust route of dissemination for the music throughout the city. It was the success of Sugar Hill Gang’s Rapper’s Delight, issued on a small independent label in 1979, that brought rap to national attention and gave the genre its name. MC Kurtis Blow’s The Breaks (1980), and Rapture by the pop group Blondie (1981) are also milestones in the early history of rap.
During the first part of the 1980’s the entertainment industry was slow to realize rap’s potential and it was left to entrepreneurs like Russell Simmons to popularize rap and to demonstrate its long-term commercial viability by organizing national hip-hop concert tours and producing hits by many of the most important artists of the period including L.L. Cool J, Slick Rick, and Foxy Brown. Independent films like Wild Style, Beat Street, and Style Wars, introduced hip-hop to a global audience. Rap music videos began to be produced and all-rap radio stations began broadcasting. Independent labels gained ground and rap was incorporated into the established recording and distribution industry. By 1986 hip-hop culture was the most successful popular music in the nation, and rap had developed in three general directions. Pop rap (or party rap) is light, danceable, and often humorous; it quickly became a crossover genre, generating national hits by Salt-N-Pepa (the first successful female rap group), MC Hammer, Vanilla Ice, and many others. Rock rap combines the vocalizations of rap with the sounds and rhythms of rock bands. The hip-hop trio Run-D.M.C. brought rap rock to national prominence with King of Rock (the first hip-hop platinum album, 1985). The Beastie Boys, the first white rap group, appealed to a youth market by smartly combining humor and rebellion in songs from their 1986 debut album Licensed to Ill. Rock rap set the stage for other hybrids that flourished in the 1990’s such as Rage Against the Machine and Linkin Park. Socially conscious rap portrays and comments on the urban ills of poverty, crime, drugs, and racism. The first example is Melle Mel’s The Message (1982), a series of bleak pictures of life and death in the ghetto.
New school rap dates from 1986 when Rakim and DJ Eric B introduced a vocal style that was faster and rhythmically more complex than the simple sing-song couplets of much old school rap. Writers (rap poets/performers) in the new “effusive” style, notably Nas, employed irregular poetic meters, asymmetric phrasing, and intricate rhyme schemes, all of which added depth and complexity to the flow. Much of the new music (and new styles of graffiti and dance) came from the West Coast, and increasingly from the South and Midwest. Hip-hop culture was spreading to Europe and Asia as well.
The accompaniment for rap also became more complex and varied. CD’s largely replaced vinyl records and samplers became commercially available. Producers working with samplers, programmable drum machines, and synthesizers could, with the push of a button, mix and modify sounds imported from a virtually unlimited selection, and so largely replaced DJs as the creators of rap’s musical accompaniment. The New York production team Bomb Squad and producers RZA and DJ Premier layered multiple samples to create dense, harmonically rich textures and grating “out of tune” combinations of sounds, while West Coast producers developed G-funk by using live instrumentation and conventional harmonies associated with funk music.
The year 1988 was an important turning point for rap. The Source, the first magazine devoted to rap and hip-hop, appeared that year, and was soon followed by Vibe, XXL and many others. The first nationally televised rap music videos on Fab Five Freddy’s weekly show “Yo, MTV Raps!” brought hip-hop images and dances to national attention. That same year four new rap genres emerged, partly in response to worsened social conditions in black urban communities: unemployment, drastic cutbacks in education, the crack cocaine epidemic, proliferation of deadly weapons, gang violence, militaristic police tactics, and Draconian drug laws all leading to an explosion in the prison population. Political rap was led by writer KRS-One, with Boogie Down Productions whose album By All Means Necessary explored police corruption, violence in the hip-hop community, and other controversial topics. On the West Coast, N.W.A. were cultivating harsh timbres and a raw angry sound in their nihilistic tales of Los Angeles police violence and gang life in Straight Outta Compton, the first gangsta rap album. Jazz rap, characterized by use of samples from jazz classics and positive, uplifting lyrics was introduced by Gang Starr (DJ Premier and MC Guru) and hip-hop group Stetsasonic. Another answer to West Coast gangsta rap was New York hardcore rap, led by producer Marley Marl whose hip-hop collective The Juicy Crew achieved their breakthrough with the posse track The Symphony. Each genre had important followers. Black nationalism informed the political lyrics of Public Enemy (led by Chuck D) whose critical and commercial success in 1988-90 proved the crossover appeal of the new wave of socially conscious rap. Houston-based gangsta rap group The Geto Boys combined ultra-violent fantasies with cutting social commentary in a blues-inflected style that came to characterize the “Dirty South” sound in their 1990 debut album. Jazz rap’s Afrocentric lyrics, fashion, and imagery were shared by important new rap artists Queen Latifah and Busta Rhymes. Latifah provided a feminist response to the often misogynist lyrics of male rappers. Wu-Tang Clan’s Enter the Wu-Tang (1993) reclaimed New York’s reputation for cutting-edge hardcore rap. The minimalist production style on the album by this Staten Island group was much imitated through the next decade.
In the 1990’s a style called new jack swing originating with producers Teddy Riley and Puff Daddy integrated R&B into rap and softened rap’s hardcore content while retaining the edge of black street culture. Notorious B.I.G.’s Juicy from Ready to Die (1994) exemplifies the laid-back vocal delivery and slower tempo that characterize new jack. Lil’ Kim’s rap on Gettin’ Money captures the “ghettofabulous” image of the new jack rapper in lyrics that mix gats and six-shooters with Armani and Chanel. The song draws on the iconic American figure of the Mafia don to create metaphors that celebrate materialism and luxury. Tupac Shakur and Notorious B.I.G. were the most critically acclaimed and best-selling rappers during the middle of the 1990’s. Shakur was murdered in 1996 and Notorious B.I.G. in 1997. In the eyes of many fans, hip-hop had lost its two greatest artists. Three important figures—Eminem, Jay-Z, and Missy Elliott—led rap into the new millennium.
