Documentary about progressive music and the generation of bands that were involved, from the international success stories of Yes, Genesis, ELP, King Crimson and Jethro Tull to the trials and tribulations of 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, and quintessentially English, literary influences.
It looks at the psychedelic pop scene that gave birth to progressive rock in the late 1960s, the golden age of progressive music in the early 1970s, 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. Contributors include Robert Wyatt, Mike Oldfield, Pete Sinfield, Rick Wakeman, Phil Collins, Arthur Brown, Carl Palmer and Ian Anderson.

20 years ago, two astronomers made a remarkable discovery, one which would change the way we view the universe for ever. A planet outside our solar system, orbiting a distant star - an exoplanet. Since then, we have found worlds where it rains diamonds, ones that boil at 3,000 degrees centigrade and even a world with four suns in its sky. But the big question is - will we ever find another Earth? As we close in on the discovery of the 2,000th planet outside our solar system, or exoplanet, we investigates the techniques that are revealing so much about these alien worlds. The documentary asks if we are really any closer to finding another world like our own - a second Earth.
