Journey to the Centre of the Eye by Nektar

Journey to the Centre of the Eye is the debut album from English progressive rock band Nektar that came out in November 1971. Though formally divided into 13 tracks, the entire album consists of a single continuous piece of music, with some musical themes which are repeated throughout the work. Because of its narrative nature, it has been called a rock opera and/or dense concept album. The story follows an astronaut who, while on a voyage to Saturn, encounters aliens who take him to their galaxy, where he is suffused with knowledge and wisdom. It is usually interpreted as a commentary on the nuclear arms race.
