If you were a fan of Boston-pop/grunge-splosion major-label casualties the Dambuilders, Joan Wasser’s solo work may surprise you. Or make you wonder why they didn’t let her sing more: not that her violin wasn’t as mighty and rocking as a bow on catgut can be, but Wasser’s real weapon is her voice. Her 2006 debut under the name Joan as Police Woman, Real Life (Reveal), is searing and deeply melancholic–even when Wasser’s singing about the joy and promise of true love, she sounds spent from a life traveling rough roads. The songs are mature and a little torchy–surprisingly soulful for someone who’s spent more than a decade in the punk scene. Judson Claiborne opens. a 9 PM, Schubas, 3159 N.
