This time around on "Rhythm Roulette," Mass Appeal linked up with the one and only, El-P. The Def Jux general blessed us with the opportunity to gain some insight on the process, which has helped him make classic material since 1993. After heading to a hole-in-the-wall record shop and picking out some dusty old warped records, El showed us how to make something out of nothing/s, starting with his rusty, self-fixed, ASR-10.
