The debut album from 2006’s most unexpected duo—Goodie Mob’s CeeLo Green and underground-rap super-producer Danger Mouse—sounds like the past and future at once, an ecstatic blend of experimental beats and golden-age soul. “Go-Go Gadget Gospel” is a burst of frantic breakbeats, exuberant horns and gospel-choir wails of “I’m free!”, while “Crazy”, a super-sized pop smash that sacrifices none of the freak funk, sees the duo probing the strange recesses of the human psyche.
