On this day in 1973, legendary DJ and hip-hop pioneer Kool Herc DJed his sister’s back-to-school party at their high-rise apartment at 1520 Sedgwick Avenue in the Bronx, New York, and the world was never the same again.

There, Herc doubled up the instrumental “breaks” of the songs to extend them longer, and breakdancing was born. According to Google’s Doodle Blog, Herc’s friend Coke La Rock, spoke over those sections as a way to further liven up the performance, creating what we know today as the number one music genre is America: hip-hop.

Google is celebrating the 44th anniversary of DJ Kool Herc’s instrumental break with a virtual DJ tutorial. The doodle, which you can find here, leads into a brief lesson on hip-hop’s origins in New York block parties, courtesy of Fab 5 Freddy. From there, you take charge of the decks. Using an interactive turntables and record crate, you can emulate the basics of crossfading, beat matching, scratching, and more, all to a soundtrack including iconic hiphop essentials from George Clinton, Grandmaster Flash, the Isley Brothers, and more.
