Few recent bands have rocketed into the public spotlight with as much vigor as Alabama Shakes, a quartet of Southern garage-soul upstarts who are led with swaggering attitude by vocalist Brittney Howard. On their debut, Boys & Girls, Howard’s soulful sucker punch won an instant audience by recalling hard-luck howlers from the '60s like Otis Redding and Janis Joplin. This exclusive session captures the band playing tracks from their debut with the smoldering intensity of their live show. The unhinged energy allows some of the lesser lights from Boys & Girls, like “I Ain’t the Same” and “Heartbreaker,” to steal the show.
