A couple years ago I tried to track down the featured screening of the Oakland Underground Film Festival. It was supposed to be in an abandoned building on the Alameda Army base. Turns out it was too underground for me apparently because after going to where I was directed and walking around for almost half an hour - I still couldn't find it!
This year thankfully their venues are a bit more obvious, but the films they are screening continue the tradition of being super cool and undergroundy.
