I was interested in this for some hard to find performances of Philip Glass. The down side was that the performance of Mad Rush is not the complete piece. It is only the beginning and then the very end, with the majority of the piece missing. The rest of the film is okay, but a bit sporadic and incomplete feeling. These are not standard performances, but instead it is a blended continuous flow of partial songs and random images. There are also some interjections of random images and footage of unexplained orgin, perhaps meant as an artistic abstract expressionist piece. Unfortunately, there is a fine line between abstract media art and just plain random, and boring, nonsense. I suppose its something that you have to watch and decide for yourself, if it was worth your time, or if you should have been doing something more productive like doing the laundry.
