Known as the Drama King (aka Slap Your Favorite DJ), DJ Kayslay rose to the top of his field by refereeing some of the most talked-about MC battles of the early 2000s, most notably Jay-Z versus Nas and 50 Cent versus Ja Rule, on his Streetsweeper mixtape series and later on his Hot 97 radio show, The Drama Hour. Born Keith Grayson, the gully loudmouth grew up with his grandparents in Harlem's East River Houses, where at an early age he befriended Alberto Martinez, who would later become the legendary drug dealer Alpo.
