Everybody went crazy for "Crazy"," the Gnarls Barkley debut smash that hovers seductively between eras and genres, hitting a chord with everyone from indie rockers and hip-hop headz to teenyboppers and their great-grandparents. But "Crazy" was just one of the pleasures offered up on Cee-Lo Green and Danger Mouse's debut. Blending spaghetti Western soundtrack music, Motown, club-savvy dance beats, rock and gospel, St. Elsewhere seemed to take like a little bit of everything while resembling nothing else out there – a primer on 20th century pop that heralded a brave new musically polyglot 21st century. Bonus: they performed in Star Wars outfits.
