The first disc is perhaps the best and most complete collection of the May '68 demos. The sound quality is pretty good and all of the tracks I've ever heard are all here. The second disc is mainly filler and pretty much a waste of time. It's mostly recordings made during the recording of Revolution when they left the tapes rolling. It gets painfully boring very quickly.
