If you belong to the Hawkwind/British psych-blues school of physics, then you know that the search for outer space is a labor of mind-numbing repetition. Olympia, Wash.’s Nudity is well-equipped for such interstellar travel. Judging by the band’s debut LP, The Nightfeeders—which includes one sidelong 21-minute psych jam and an equally exploratory B-side remix—the trio’s academic background must involve at least one master’s degree in vaporizer technology and a Ph.D. from the Motorhead research institute. Here, thick and rusty garage-rock riffs are extended ad infinitum over the metric pounding of the rhythm section, sending Nudity up and out of Earth’s gravitational pull and on its way to penetrating the heliopause. Nudity performs with Vincent Black Shadow, Insect Factory, and Lexie Mountain at 9:30 p.m. Wednesday, April 23, at the Velvet Lounge, 915 U St. NW. $9. (202) 462-3213.
