August 11, 1973. Cindy Campbell throws a back-to-school party in the rec room of 1520 Sedgwick Avenue, the Bronx. Her brother Clive — DJ Kool Herc — runs two turntables side by side, finds the percussion break in James Brown's Give It Up or Turnit a Loose, and switches between two copies to extend it. The "merry-go-round" technique. The break loop. Hip-hop's clock starts here.
Within five years a vocabulary is in place: Afrika Bambaataa founds the Universal Zulu Nation. Grandmaster Flash develops backspin, cutting, and the "clock theory" for finding breakpoints. The MC — at first an emcee announcing the DJ — moves to the center. Sugarhill Gang's "Rapper's Delight" (1979) is the first rap record on a Billboard chart. It uses Chic's "Good Times" as its bed and runs over 14 minutes long.
Sugar Hill Records (Englewood, NJ) signs the Sugarhill Gang, then Grandmaster Flash & the Furious Five, whose The Message (1982) is the first rap record about something other than the party — Melle Mel's verses about urban decay, drugs, and dead-end work redirect the genre toward social document.
Afrika Bambaataa & Soulsonic Force's Planet Rock (1982), built on Kraftwerk's Trans-Europe Express and Roland TR-808 drums, is the founding record of electro. Kurtis Blow becomes the first rapper signed to a major label (Mercury, 1979). Run-DMC, three kids from Hollis, Queens, sign with Profile in 1983 — and Run-D.M.C. (1984) replaces disco beats with stark drum-machine programming and rock guitar samples.
A short window — roughly Run-DMC's Raising Hell (1986) through Wu-Tang's 36 Chambers (1993) — that produced more durable records than any comparable stretch in pop history.
Raising Hell (1986) — Aerosmith collab "Walk This Way" pushes rap onto MTV.
Radio (1985), produced by Rick Rubin in an NYU dorm. Mama Said Knock You Out (1990).
It Takes a Nation of Millions (1988). The Bomb Squad's collage production. Chuck D + Flavor Flav.
Paid in Full (1987). Rakim invents internal rhyme as we know it.
3 Feet High and Rising. Daisy Age, Prince Paul production.
The Low End Theory (1991). Q-Tip + Phife Dawg over Ron Carter bass.
Enter the 36 Chambers (1993). RZA's stripped sound; nine MCs; kung-fu flicks.
Illmatic (1994). Ten tracks, multiple producers, perfect.
Ready to Die (1994). Bad Boy Records · Sean Combs.
1986. Schoolly D's P.S.K. (What Does It Mean?) — Philadelphia. Ice-T's 6 in the Mornin' follows. In Compton, N.W.A. — Eazy-E, Dr. Dre, Ice Cube, MC Ren, DJ Yella — release Straight Outta Compton in August 1988. Two and a half million copies. The FBI sends Ruthless Records a warning letter about "F— Tha Police."
Dr. Dre's The Chronic (1992) — built on P-funk samples, live G-funk synths, Snoop Dogg as the new voice — defines West Coast for the rest of the decade. Tupac Shakur (1971–1996) and Suge Knight's Death Row Records become the dominant force; the East Coast/West Coast feud peaks with the murders of Tupac (Las Vegas, Sept '96) and Biggie (Los Angeles, March '97): Biggie's killing remains unsolved; a suspect was charged in Tupac's killing in 2023.
Atlanta-based OutKast's Aquemini (1998) is the first widely-acclaimed Southern rap masterpiece. Stankonia (2000) and Speakerboxxx/The Love Below (2003) put them at the top. UGK (Bun B and Pimp C) had been making "country rap tunes" in Port Arthur, TX since 1992. Three 6 Mafia from Memphis built proto-trap from horror-movie samples and 808 sub. By the late 2000s — T.I., Lil Wayne, Gucci Mane, Young Jeezy — Southern hip-hop is hip-hop. Atlanta producers Lex Luger, Zaytoven, Metro Boomin codify the trap sound that becomes pop's default rhythm.
By the 2010s the geography flattens. Kendrick Lamar's good kid, m.A.A.d city (2012) and To Pimp a Butterfly (2015). Drake from Toronto. J. Cole. Kanye West's My Beautiful Dark Twisted Fantasy (2010). Tyler, the Creator. Kendrick wins the Pulitzer in 2018 for DAMN. — the first non-jazz/classical winner.
By the 2000s the form has been localized everywhere. UK — grime in East London (Wiley, Dizzee Rascal's Boy in da Corner, 2003; Skepta), drill in Brixton. France — IAM, MC Solaar, Booba. Korea — Epik High, Tablo. Japan — Nujabes, Shing02. Brazil — Racionais MC's. Senegal — Daara J. Nigeria — Falz, Olamide. South Africa — Die Antwoord, Cassper Nyovest, Nasty C. The breakbeat has become the world's default vernacular.
The four classical elements per Bambaataa: DJing, MCing, B-boying, graffiti writing. A fifth — knowledge — is sometimes added.
