I've been a fan of Evan Mather's films since we screened A Necessary Ruin--a glimpse of short, strange life of Bucky Fuller's Union Tank Car Dome outside Baton Rouge--at Dwell on Design this year. I'm quite happy to let all Bay Area Dwell fans know that Evan will be back in San Francisco tonight to screen A Necessary Ruin and a couple other films as part of the AIA San Francisco's Architecture and the City festival. I'll be onstage with Evan chattign after the screening. Come down for the free event (register here) and stay for our chat and some audience Q and A. That's tonight, Wednesday the 22nd at 6:00 PM in the theater downstairs at the main branch of the San Francisco Public Library.
