Atlanta’s Waka Flocka Flame — the name comes partly from a Fozzie Bear catchphrase — has charisma enough for a dozen MCs. Which is good, since his skills are negligible. On his debut, Waka reduces hip-hop to a carnival-barker routine, blasting out exclamations (“Yay!” “Bang!”) over bristling beats by producer Lex Luger. Waka barely bothers to write rhymes, but Flockaveli is hypnotic, focusing attention on the details beneath the bombast. In songs like “Bustin’ at ‘Em,” you hang on every twist of Waka’s raised voice while waiting — for a second or two at most — for the next “Bow!” to come crashing down.
