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.

Focuses on the fierce rivalry that took place in the laboratories in Britain, Holland, France and Poland as they sought the ultimate extreme of cold.

In episode 3, Artemis arrives on the exoplanet Minerva B, but will she find evidence of life? This is a vision of our future, the fateful day in a far-flung corner of the universe, when a probe from Earth initiates the first descent onto an alien world, looking for proof of life beyond our solar system.
There are no witnesses, no cheering crowds in the control room. A decade or more will pass before news finally reaches us, back across the dark oceans of space.
