Celebrate this year's Genius Award winners—see page 21 to learn all about them—with music by Velella Velella and the Blow, Seattle's precision book cart drill team, a bevy of librarians, booze, and dancing. It all happens in the Central Library, which sparkles like a diamond and is a building built from, and filled with, genius. (Central Library, 1000 Fourth Ave, www.thestranger.com/genius. 9:30 pm, free, 21+.)
