"Curved Air are a pioneering British progressive rock group formed in 1970 by musicians from mixed artistic backgrounds, including classical, folk, and electronic sound." More here Wikipedia Stuart Copeland (later of Police) on drums.
Early copies of the album with special vinyl "The album was the first vinyl picture disc as a limited edition of 10,000. Picture disc technology was in its infancy and this resulted in a level of surface noise. The disc was re-issued in conventional album format (the "Green Label" edition), with a photo of the original picture disc on the album cover." http://en.wikipedia.org/wiki/Air_Conditioning_(album)
