It has been several months since Crawl Space hosted one of its intimate little slide shows, which are like a college lecture and a party in one. Happily, they're back. This one's under the heading "The Built Environment" and features Portland sculptor Jenene Nagy, who is showing at the gallery; Seattle's Susan Robb (a Stranger Genius Award winner, now showing at Lawrimore Project); photographer Adam Satushek; and media artist Thom Heileson. Crawl Space is small, so get there early. (Crawl Space, 504 E Denny Way, #1, 201-2441. 7:30 pm, free, all ages.)
