Four bands, zero filler. The highlight is Numbers, from San Francisco, who play slow-churning, sun-soaked synthedelic pop and have a new album, Now You Are This, on Kill Rock Stars. But the local support is just as impressive, from the sneering postpunk spite of Partman Parthorse to the lo-fi fuzz assault of the Intelligence to the no-wave death dub of Flexions, featuring the outré guitar skills of Devin Welch (of Blood Brothers/Chromatics/Shoplifting renown). All killer. (Sunset Tavern, 5433 Ballard Ave NW, 784-4880. 9 pm, $8, 21+.)
