Named after the thriving rap subgenre he popularized, Lil' Jon's Crunk Juice makes no claims to be anything but XXX-rated, hip-hop mosh pit music. Three 6 Mafia's crunked-out compositions may predate Lil' Jon's, but Jon's unique production methods continue to dazzle on cuts like "What U Gon' Do," where protégé Lil Scrappy's vocals create jarring audio effects. The trademark futuristic blend of Miami bass, Jamaican dub, electronica, and punk--littered with call-and-response chants--is in full force on "Crunk Juice," "Get Crunk," and "Da Blow." More impressively, he's broadened his crunk palette to include a brilliant rocked-out Rick Rubin collaboration, along with more conventional R&B tunes featuring Usher and R. Kelly--he even looks to D.C.-style go-go beats for inspiration on "Aww Skeet Skeet." The vulgar yet hilarious Chris Rock comedy cameos help make this album a winner, even if it's intentionally zany and lyrically vacuous. --Dalton Higgins
