Aqualung

Aqualung is the fourth studio album by the rock band Jethro Tull. Released in 1971, Aqualung, despite the band's disapproval, is regarded as a concept album featuring a central theme of "the distinction between religion and God". The album's "dour musings on faith and religion" have marked it as "one of the most cerebral albums ever to reach millions of rock listeners". Aqualung's success marked a turning point in the band's career, with them going on to become a major radio and touring act. Recorded in Island Records' studio in London, it was their first album with John Evan as a full-time member, their first with new bassist Jeffrey Hammond and last album featuring Clive Bunker on drums. The album is something of a departure from the band's previous works, featuring more acoustic material than previous releases; and-inspired by photographs of homeless people on the Thames Embankment taken by singer Ian Anderson's wife Jennie-contains a number of recurring themes, addressing religion along with Anderson's own personal experiences.
