Originally released in November 1971, the album was the first release by the band and featured a continuous piece of music divided into 13 tracks.

This impressive conceptual science fiction inspired work, which was interpreted as a commentary on the nuclear arms race, was the band's first album release and originally appeared in Germany, the country where the British band were formed and were based, enjoying commercial success and building Nektar's loyal following.

This 2CD edition features a completely new remaster of the original stereo album mix (from the original master tapes), plus both tracks from the 'Do You Believe in Magic' single issued in April 1972.
