Jawbox has come a long way since its first recording, a 1989 contribution to a compilation for the venerated punk ’zine MaximumRockNRoll. Seven years and a few lineup changes later, and despite a disappointingly slick new album, the feisty quartet is still capable of spine-tingling live performances. After two months on the road, Jawbox returns home tonight with the Dismemberment Plan, a quirky combo signed to Jawbox’s own DeSoto label, whose volatile pop grooves are in constant danger of combusting with the silly vitriol of vocalist Travis Morrison’s entertaining rants. Check ’em out, along with Skeleton Key at 9:30 p.m. at the 9:30 Club, 815 V St. NW. $7. (202) 393-0930. (Amy Domingues)
