Brace yourselves, performance people. The fall blitzkrieg of theater and dance is whipping down on us like a hurricane—and that means parties! Velocity kicks off with a three-day party starring more than 30 artists “filling every nook and cranny with dance, music, film, and visual spectacle.” We’re talking hiphop, Butoh, funky modern, spooky ballet, draggy/genderqueer stuff, and more from Ezra Dickinson, Genius Award nominees Zoe Scofield and Juniper Shuey, Markeith Wiley, Maureen Whiting, Beth Graczyk, Spectrum Dance Theater, and shitloads more. (Velocity Dance Studio, 1621 12th Ave, www.velocitydancecenter.org, 8 pm, $10–$50, Sept 14–16)
