The little hideaway behind a fence on Capitol Hill—it was once Crawl Space, the great art engine—is back in business. Renamed Ghost Gallery, its first high-profile opening is tonight. The show, ACTION!, is an explosion of video, light, and sound installations by Seattle artists (Amanda Manitach, whose heroes all died of syphilis; huge-brained Keith Tilford, coming out of seeming hiding; and others). Sponsors are 911 Media Arts Center and the Warhol Foundation, providing art as well as hot dogs, burgers, and beers. Head up the hill to the Unicorn for the afterparty, a "psychedelic freak-out" with prism glasses provided, by local design masters Dumb Eyes. (Ghost Gallery, 504 E Denny Way, www.ghostgallery.org. 5–8 pm, free.)
