This is a “Mondo”-style movie, today this genre would be called “docutainment”. The subject is life in Hollywood during the second half of the 60s. With this southern California theme we get lots of surf-music along with some surfing and skating. I find the whole thing quite entertaining, and think it projects a vision of a town in transformation, when some people had other plans than becoming a movie-star or starlet.
If I’m remembering correctly the guitars are played by Davie Allan.
