Question: What tie binds performers such as burlesque diva Simone de la Getto, rock-theater outfit Jessica Fudim’s Dance Animals, an actual 50-Guitar Orchestra, and other equally-outrageous acts like Dyspecific, Shawna Virago, Sara Kraft, and Audrey Howard and the Misters?

Answer: They’ll all pitch in Friday from 8 p.m. to midnight for a benefit show for CounterPULSE dubbed “Rock 4 Art.” It’s the third annual benefit thrown by CounterPULSE, an alternative-arts space that has sworn a “commitment to uncategorizable, cutting-edge performance.”

Diamond Daggers mainstays Amelia Mae Paradise and Sarah Paradise are masters of ceremonies; the event also features a performance of Carrie Baum’s “Exit Sign: A Rock Opera.”

CounterPULSE is located at 1310 Mission St. (at Ninth Street), San Francisco. Tickets run on a sliding scale from $8 to $20. Call (800) 838-3006 or visit www.brownpapertickets.com. For more information, visit www.counterpulse.org.
