This paper intervenes into the histories of two musics that have traditionally been narrowly studied along racial lines. While hip hop pioneers like Bambaataa, Grandmaster Caz, and Fab 5 Freddy, and their punk counterparts like Blondie, the Tom Tom Club, and the Clash have all emphasized how the two genres are inseparably linked, music historians and journalists have neither stressed, nor, in most cases, mentioned hip hop and punk’s many connections. Yet while the punk and hip hop scenes influenced each other, I maintain that punk rock wielded greater influence over hip hop. After all, in order for hip hop to expand its fan-base, and allow hip hoppers to make money off their craft, hip hop had to come downtown. This paper explains how coming downtown did much to commercialize hip hop, changed the Bronx music scene, and helped create modern hip hop culture by bringing together the previously disparate art forms of graffiti, b-boying, DJing, and MCing.
