FILM: This month's Incredibly Strange Picture Show features the zany Zach Galifianakis: Live at the Purple Onion. Filmed in 2005, Galifianakis' performance at SF's famed Purple Onion is said to still be his funniest. The footage of the stage show is accompanied by a tour diary and an interview between Brian Unger and Zach's "twin brother." It's also the Incredibly Strange Picture Show's 5th anniversary, and there will be pre-show entertainment and giveaways with host John Hamilton.

ART: Southern Exposure's Mission Voices Summer youth, artists, and community partners will exhibit their work in El Grito de la Misión, which was developed over a six week intensive workshop exploring "self-representation and identity in comparison to abstract or rigid representation by looking outside and inside the box." Tonight's opening event consists of new work and installations, interactive performance works, food, and refreshments.

MUSIC: Canada's Mother Mother combines upbeat and off-beat boy-girl harmonies, which one critic says even Queen would be proud of, with interesting instrumental experimentation. Oakland's high-energy HIJK and SF's foma also perform.
