To his credit, Blur's Damon Albarn the auteur behind pop's finest cartoon band since the Archies didn't want to rehash the sardonic sleepy-time dub of Gorillaz's 2001 self-titled left-field hit. With Grey Album producer Danger Mouse at the knobs, the follow-up Demon Days is spookier, blippier, and more on edge. It's also not as cohesive. Some of the guest turns (De La Soul on ''Feel Good Inc.,'' Happy Mondays frontman Shaun Ryder on ''DARE'') work; others (Dennis Hopper's narration on ''Fire Coming Out of the Monkey's Head'') are one-listen experiences. Tailor-made for iPod pruning.
