ART: In celebration of Beatles Day, Space Gallery presents Revolution 9.9.9, featuring artwork by Sean Ward, Marco Mejia, Julia Sanders, and Tandy Kunkle, which explores the band’s unmatched impact on popular culture through paintings, drawings, photography, sculpture, film, and performance. The event features two live sets by The Vows, the first of which will celebrate the psychedelic Beatles, and the second -- after a drastic and radical costume change -- will feature Beatlemania-era mop tops. There will also be a Beatles look-alike contest at Midnight. The art exhibit runs through September 14.
