Watch HDToday. In 2001, the Los Angeles club the Root Down put on their first of a three part series called "Sound Clash." It featured Madlib and Cut Chemist going head to head; beat for beat for respect in front of a packed club. Each of the tracks had never been released and with each of the three rounds, the excitement rose.. Mochilla never intended to release this DVD but since the tragic passing of DJ Dusk, they felt it was important to honor his legacy and share his gifts. This is for him: no edits, no overdubs, and no interruptions - just raw Hip Hop at its most exciting, vital and real.
