I finally got a chance to see this movie. Some will like it; I was not particularly impressed. It should have been named something else because it spent too much time on the Chamberlin (the M1 an obviously great machine) and actually very little time on the Mellotron and the bands that made it famous. I also would have liked to see more on the resurrection. 80 minutes is not enough time to properly cover this subject.
I'm not sure why the effort was made if it was going to be so obviously incomplete.
