D.C.’s own lesbian pop-rocker, Mara Levi, will compete as a solo artist against nine rock bands during a “Battle of the Bands” event in suburban Virginia. The deck seems stacked against her, but Levi is a fantastic performer and she’s doing her darnedest to get her fans out, since the crowd picks the winner of this Gorilla Music production. Sunday, July 26, at 4 p.m. Jaxx Nightclub, 6355 Rolling Road, Springfield. Tickets are $10. Call 703-569-5940 or visit www.jaxxroxx.com.
