The DJ that started it all. Kool Herc, justifiably called the Godfather of Hip Hop, started a revolution when he used two turntables back and forth to loop the funkiest parts of popular dance records at his early '70s throw-downs in the South Bronx. The break-beat was born, leading the way to breakdancing. Meanwhile, Herc and his crew's rhythmic call-and-response chants on the mic were the early blueprint for rapping. Without Herc, this list wouldn't even exist.
