The Dead Weather’s final stop on their summer tour was Tuesday night under threatening skies in Brooklyn’s Prospect Park. Thankfully the rain held off, but the thunder and lightning were in full effect on the stage. Openers Harlem from Austin, TX played a nervous opening set of their stripped down fifties style surf/garage pop. Focusing on their newest album, Hippies, they seemed to mumble and act a bit jittery until things picked up for final few tunes. This could be traced to Curtis O’Mara coming out from behind the drums to sing and play guitar on “Friendly Ghost” and “Faces”.
