This film is straight-ahead footage of Santana, the Grateful Dead, and the Jefferson Airplane playing at The Family Dog in 1970. Each band does two songs, followed by a jam at the end featuring musicians from all of the bands.No interviews, no special editing techniques (OK, a few...), no brilliant cinematography -- you see the bands play, and that's it. (That means that if you like these bands circa 1970, you'll probably like this film. If you don't like these band, there is nothing for you here!)
