Big Boi fills his third solo album with punchy, delirious wordplay that dazzles with Dirty South touchstones. “All Night” features a jaunty piano rag and goodtime hook. Snoop Dogg and Big Boi go drawl-for-drawl on “Get Wit It.” “In the South” finds Gucci Mane and the late Pimp C uniting on a track. And when Big Boi checks out the action in the dance tent, the party goes into overdrive (“Chocolate,” “Overthunk,” “Freakanomics,” “Mic Jack”).
