Here's what's going on today (Saturday, Sept. 15): The Savannah Music on Film Festival continues with three screenings today at Muse Arts Warehouse. The 2 p.m. feature is the Japanese punk drama Iden & Tity; at 5, it's Black Francis' The Golem, a rare German black and white silent drama with compelling original score by Pixies frontman Frank Black. The evening show - at 8 - is Craig Zobel's disturbing docu-drama The Great World of Sound. Want more?: Crooner Ruben Studdard sings in a free concert at 7 p.m. on Tybee Island's North Beach. KidSyc@Brandywine are at Congress Street Social Club, Cusses and Triathalon (with Roland) play the Jinx, the Chinas are at Live Wire, and Whaleboat plays Screamin' Mimi's with A Brilliant Lie. The Wormhole's got Guttermouth and Powerball. Citizen Kane is screened at the Trustees Theater at 7, there's a party and concert at Woody's Skate Park from 1 to 5, and, oh, yes, a bunch of good seats have been released for tonight's otherwise sold-out Elton John concert at the Civic Center (available at the box office starting at 1 p.m.).
