Killing time before a lecture a couple of weekends ago, we wandered over to an art exhibit across the street and literally ran into a nude couple in the building's very small elevator. In the course of some very *focused* conversation during our ride to the 3rd floor, we learned they were rehearsing for a performance by La Pocha Nostra, a non-profit performance collective based in the Mission in SF. We returned that evening to see the group in action. Click here to view Jaeha Yoo's Performance video. Note -- brief nudity starting around 1:20.
