The tape has a very warm quality, and I found out why - it was all filmed on 16mm by Leonard Eisenberg (who took those great shots of Hendrix at Woodstock), so it is like watching a movie.
The scenes in the hills of Pennsylvania with Cesar are a treat to watch. The music on the video features guitar by Cesar.
