不列颠前卫摇滚-对三个运动的一个观察

　　Prog Rock Britannia is a comprehensive, feature-length documentary about progressive music and the generation of bands that made it - from the international success stories of Yes, Genesis, ELP, King Crimson and Jethro Tull, to the trials and tribulations of the lesser-known bands such as Caravan and Egg.
　　The film is structured in three parts, charting the birth, rise and decline of a movement famed for complex musical structures, weird time signatures, technical virtuosity and strange – quintessentially English – literary influences.

　　It looks at the psychedelic pop scene that gave birth to progressive rock in the late Sixties, the golden age of progressive music in the early Seventies – complete with drum solos and gatefold record sleeves – and the over-ambition, commercialisation and eventual fall from grace of this rarefied musical experiment at the hands of punk in 1977.
　　The documentary is a provocative, humorous but affectionate re-appraisal of a music that was the value system of an all-too-brief period in British popular music
