The Lashes haven't performed since their "comeback show" at last summer's Bumbershoot. Months prior, guitarist Eric Howk had an accident and was paralyzed from the waist down. The band's future was anyone's guess, but the Lashes surprised all when they (including Howk) took the stage last August with more enthusiasm than ever. They've got a new record called Thank You (Side A), a collection of strong power-pop tunes they'll be celebrating tonight. (Vera Project, Seattle Center, 956-8372. 7:30 pm, $10, all ages.)
