Coming from the ex-communist block this concert for me marks the end of an era. Yes- it's an old recording so the quality is not superb, but it's still well filmed and the combination of different artists actually works quite well.
This film is a very good insight of the history of one of the most successful Pink Floyd albums. The interviews are quite interesting and it's funny to see how the artists fell victim to their own success. If you're a Floyd fan you should definitely get it.
