SoCal turntablist J-Rocc (a.k.a. Jason Jackson) isn't a household name-except in houses that contain enough records to cause hernias in Olympic weightlifting champs. He's best-known as a founding member of the Beat Junkies, a crew of golden-reflexed crate-diggers-including DJs Babu, Rhettmatic, Shortkut and D-Styles-that surfaced in 1991 with a repertoire of decks-terous tricks that would make your head spin (typically on the floor). YouTube has plenty of prime footage of J-Rocc and Beat Junkies making bizarre and funky sounds with only their hands, vinyl and Technics, but this Stones Throw Records mainstay is even better in the flesh.
