One of the original turntablists, J-Rocc founded the Beat Junkies in 1992 with Melo-D and Rhettmatic, but has done just as much on his own as in a group setting. Born Jason Jackson, he began DJing in the mid-'80s with a California group named PSK. Soon after forming, the Beat Junkies became a seminal force in the rise of instrumental hip-hop. Beat Junkies mixes and studio material continued to pour out. J-Rocc's first widely issued mix album, Walkman Rotation, appeared in 1998 on Conception. After touring as the DJ for Madlib's live shows, J-Rocc released his first album of productions, Some Cold Rock Stuf, in 2011 on the Stones Throw label. ~ John Bush
