1520 Sedgwick Avenue

Overview

Bronx apartment building whose ground-floor recreation room hosted the August 11, 1973 Back to School Jam, DJ Kool Herc's first public demonstration of the breakbeat technique that seeded hip-hop. The rec room gave way to larger park jams within a year or two; the building, a Mitchell-Lama affordable-housing complex, survived a market-rate conversion fight and was preserved in 2011. New York State designated it the 'birthplace of hip hop' in 2007.

1520 Sedgwick Avenue is an 18-story, 102-unit residential building in Morris Heights, completed in 1967 under the Mitchell-Lama moderate-income housing program, situated near the Cross Bronx Expressway, the Robert Moses artery whose construction had bisected and destabilized the surrounding Bronx neighborhoods a decade earlier, accelerating poverty, landlord abandonment, and gang proliferation. That geographic and social context is inseparable from what the building's ground-floor recreation room produced: a music culture forged not by the industry but by working-class Black and Puerto Rican teenagers who had been systematically deprived of recreational infrastructure. The Campbell family had emigrated from Kingston, Jamaica in November 1967, settling at 1520 Sedgwick, and Clive Campbell (who would become DJ Kool Herc) grew up watching Jamaican sound-system culture translate to the tenement stairwells and parks of the Bronx. On August 11, 1973, his younger sister Cindy organized a back-to-school fundraiser in the building's rec room, renting the space for $25 and charging 25 cents admission for women, 50 cents for men; she hand-wrote invitations on index cards. The party ran 9 p.m. to 4 a.m. Herc brought his system, two turntables, two amplifiers, and a Shure 'Vocal Master' PA with two six-foot speaker columns, up from the family's second-floor apartment, setting the DJ booth apart from the dancefloor. Playing hard funk (James Brown's 'Give It Up or Turnit a Loose,' the Incredible Bongo Band's 'Apache') he demonstrated what he called the 'Merry-Go-Round': reading the groove shadings on duplicate vinyl to isolate the drum break (the thirty-second percussive interlude dancers responded to most) and extending it indefinitely by cutting between two copies on matching turntables, producing what came to be called the breakbeat. While Herc worked the decks, his close friend Coke La Rock (born April 24, 1955) spoke over the music (shouting out friends, calling names) a style rooted in the Jamaican toasting tradition and now recognized as hip-hop's first MC performance. Attendees (or people who later claimed to be there, a distinction scholars take seriously) reportedly included Grandmaster Caz, Grandmaster Flash, Busy Bee, Afrika Bambaataa, and Kool DJ Red Alert. The rec room hosted further parties through the mid-1970s before Herc moved his sound system to larger venues, Cedar Park (near 170th and Cedar), local school gymnasiums, and eventually Manhattan venues, where the scene expanded into the crews, emcees, and b-boys who crystallized hip-hop's four elements. Grandmaster Flash and Afrika Bambaataa developed their own innovations from Herc's breakbeat foundation, and the Bronx park-jam circuit of 1974–1979 that Ewoodzie argues was the true crucible of hip-hop's conventions grew directly from what began in this rec room. The building changed hands multiple times in the 2000s. In 2007 the owner invoked Mitchell-Lama's 20-year buyout clause, triggering a preservation fight led by the Urban Homesteading Assistance Board and tenants groups; Senator Schumer organized a rally. Despite advocacy, the courts permitted the privatization. A real estate group that included Mark Karasick purchased the building in 2008 for market-rate conversion; the housing bubble's collapse and ensuing neglect put residents under threat of eviction. In 2010, the city's Housing Development Corporation provided a $5.6 million loan, enabling Winn Development and Workforce Housing Advisors to acquire the mortgage from Sovereign Bank for $6.2 million. On November 7, 2011, following a foreclosure auction with no active bidders, Workforce Housing Advisors took title; $16.8 million in rehabilitation followed, restoring affordability at 60–70% AMI for a family of four. The building remains residential today (the rec room is once again a tenant amenity, not a performance space). New York State formally designated 1520 Sedgwick 'the birthplace of hip hop' on July 5, 2007, with a nomination to the State and National Registers of Historic Places. In February 2016 a stretch of Sedgwick Avenue was renamed Hip-Hop Boulevard. New York City declared August 11 Hip Hop Celebration Day, and in 2023 the building was central to the genre's globally observed 50th-anniversary commemoration. The building's cultural weight is immense, but it remains someone's home; scholars and advocates have consistently emphasized that its preservation as affordable housing is the most authentic form of commemoration.
