Sarah Rudinoff is a self-deprecating diva. She named this high-wattage cabaret—Nick Garrison, Chris Jeffries (Stranger Genius, class of '03), Gretta Harley (of We Are Golden)—after an embarrassing college photo of herself. (The story involves a bicycle seat and grease paint, and ends like this: "All he wrote on the back of the pic was, 'This is you sometimes. Love Paul.') Expect power duets, rock 'n' roll, avant-garde classical—a little song, a little dance, a little seltzer down your pants. (The Triple Door, 216 Union St, 838-4333. 7:30 pm, $20 adv/$25 DOS, all ages.)
