Overview: The film opens at a pop festival. Drug-smoking is very much in evidence. “These fellows will answer to God” says the Rev Jack Wyrtzen, “for all the pollution and evil they have spread around the world.” “The thing about rock n roll” says Lester Bangs, “is that it is totally about adolescence, and about consumerism brought in the highest degree”. In fact, as the film begins to point out, neither of these extreme points of view is true. Tangerine Dream perform religious music in Coventry Cathedral. Stomu Yamash’ta, a spectacular Japanese percussionist, clearly has nothing to do with adolescence: and no-one could describe Mike Oldfield as the product of consumerism.
