I was very active in the early seventies and onward i and was in a number of bands over the years that were not all that different from this one. If you can pick up some coin, great, but this was not a group that I would have wanted to stay with for long. Obviously no future. Frankly, most struggling groups are very much like this. Truly talented musicians are very hard to find, particularly when they are surrounded by that huge, galloping herd of people who _think_ that they are talented. From what we see in this film the music was cliche from day one and things were pretty much a mess. What you do see is energy, a serious confusion of direction, and not much else. For these guys, it was about the fun, the exhilaration, and the head trip of performing live. Genuine talent was not really part of the equation.
This makes me think of Pete Townsend. For him it is / was about good solid songwriting, a great head for production, and a genuine talent for rhythm guitar (we are talking about drama, intelligence, an excellent sense of timing, and not trying to be something he is not.) The performances were all built on this very strong foundation and it was the attitude that gave it focus. You just don't see any of that in this band.
