(Re)claiming the spirit of ’77, such Sweetie songs as “Testosterodent” attack pathetic maledom with the vehemence, if not yet the verve, of such precursors as the Slits and X-Ray Spex. The grrrlish local quintet opens for the Jackonuts (from Athens, Ga., don’t sound it) at 8:30 p.m. at the Black Cat, 1831 14th St. NW. $5. (202) 667-7960. (MJ)
