If you are in or near San Francisco
I just went to an interesting little exhibit today, thought I would mention it in case anyone here is interested. Here is the link:
The show is called "Something's Happening Here"--it's the Bay Area Rock 'n' Roll stuff from 1963-1973. It's not a huge thing and it isn't all photography, but there are some interesting photos both from the usual suspects and some one off things. Anyway, it's cheap ($5) and interesting if you like that era music.
