Quoting from their MySpace profile:

Surf Soundtracks 1964 – 1974 Released on July 2nd on Harmless Records

Never mind the Beach Boys, Chairman Of The Board is a collection of vintage soundtracks from iconic cult surf films. Underground film makers wanted original music, a harder sound to reflect the new wilder cinematic expression now possible on the face of a wave. The soundtrack they chose to enhance this visual experimentation was the mellower stoner blues and psychedelic rock, which perfectly captured the cerebral highs of living the alternative dream. The music featured on this compilation, some of which has never been released, originates from six of these classic surf films.

I have some of the films on VHS or DVD, and some of the released soundtracks on vinyl. It’s a really great genre with a very high musical standard. And it’s something you can play to people if they ask you what music surfers listened to, in the 60s (and early 70s in this case).
