A good day to dig this one out of a dusty crate and loop it in the background as you watch NASA coverage of the last voyage of Endeavour. 'Space' - an LP by the KLF in 1990 (actually, at the time, Jimmy Cauty and The Orb's Alex Paterson). Produced in a week. Reproduced here in six parts, but available on the web in various places as a complete single free download.

Space takes the listener on a voyage through the solar system from Mercury outwards, with vast distances of empty space between worlds represented by periods of minimalist ambience and near-silence. Synthesisers, excerpts from classical compositions and nursery rhymes (including Twinkle Twinkle Little Star), sinusoidal loops, and communications from space flight controllers are among the sounds used to describe the voyage. Cauty has called Space "a record for 14-year-old space cadets to go and take acid [to] for the first time".
