Full disclosure: There is video online in which I (very sloppily) sing "Bad Romance" along with an early incarnation of Magic Mouth at a birthday party. The fearless, fun-loving spirit of the initial duo—drummer Ana Rodriguez and Peter Condra on guitar and vocals—has since evolved into a powerful quartet that threatens to match the get-down soul power of any band in this city. Brendan Scott's bass undertones and Stephfon Bartee's jaw-dropping vocals and percussion add to the band's amalgam of influences, including Latin rhythms and the holy tones of spirituals, in what the band describes as "post funk"—music that is heady, sexy, eerie, and highly danceable. Tonight marks the release of their debut EP, surely to be celebrated with style. MARANDA BISH
