Anthony Williams, a.k.a. DJ Roc Raida, has died. Even if you are not a fan of DJing, watch the clip below to see what the world has lost. I was amazed when the X-Ecutioners came to Future Primitive in S.F. and blew everyone’s mind with their choreographed acrobatics. Lots of people on the West Coast dismissed ‘em as “trick DJs,” and that’s legitimate, but tricks are entertaining and they were entertaining as hell. Rest in peace, Raida.
