Although vocal rap has become all but synonymous with hip-hop, effectively displacing DJs as the prime movers in determining the music's distinctive aesthetic, a new generation of hip-hop DJs are going it alone, approaching the turntable as a instrument in its own right. San Francisco promoter David Paul's brilliant Return Of The DJ compilation charts this continuing evolution, with sturdy, mind-bogglingly complex turntable orchestration from such names as Q-Bert, Mixmaster Mike, DJ Disk, the Beat Junkies, New York's X-Men, Z-Trip, and DJ Ghetto, among others. Fluid beats, vast, layered instrumental passages, and tons of deft scratching loosely cement the notion of a restless, DJ-based hip-hop avant-garde craving only one thing: innovation.
