If anyone is going to blow the doors of perception clean off the hinges of Seattle's underagers (and 21+s), it's going to be Brooklyn's Growing and Eric Copeland. Growing have been moving in the direction of Copeland's band Black Dice: big, ruptured, quasidanceable beats smeared with grotesquely distorted guitars and keyboards, all of which coalesce into a futuristic junkyard psychedelia. Copeland's material is even more warped and exotic, yet more perversely memorable. What a strong, deranged trip this will be. (Vera Project, Seattle Center, 956-8372. 7:30 pm, $8/$9, all ages.)
