Aqualung is the fourth studio album by the British rock band Jethro Tull, released on 19 March 1971, by Chrysalis Records. It is widely regarded as a concept album featuring a central theme of "the distinction between religion and God", though the band have said there was no intention to make a concept album, and that only a few songs have a unifying theme. Aqualung success signalled a turning point in the career of the band, which went on to become a major radio and touring act.
Recorded at Island Records' new London recording studio, it was their first album with keyboardist John Evan as a full-time member, their first with new bassist Jeffrey Hammond, and last album featuring Clive Bunker on drums, who quit the band shortly after the release of the album. Something of a departure from the band's previous work, the album features 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.
Aqualung is Jethro Tull's best-selling album, selling more than seven million units worldwide. It was generally well-received critically and has been included on several music magazine best-of lists. The album spawned two singles, "Hymn 43" and "Locomotive Breath".
Production
"My God" was recorded on 11–12 April 1970, followed by "Wond'ring Aloud" on 21 June, both at Morgan Studios. After an American tour, bass player Glenn Cornick was fired from the band, and was replaced with Jeffrey Hammond, an old friend of Ian Anderson. Aqualung would be Hammond's first album with the band. It would also mark the first time John Evan had recorded a full album with the band, as his only prior involvement was to provide several keyboard parts on the previous 1970 album, Benefit. In December, the album became one of the first to be recorded at Island Records' newly-opened recording studios on Basing Street in London. Led Zeppelin were recording their untitled fourth album at the same time. In an interview on the 25th anniversary edition of the album, Tull's bandleader Ian Anderson said that trying to record in that studio was very difficult, because of its "horrible, cold, echoey" feel. There were two recording studios at the location; Led Zeppelin worked in the smaller studio downstairs, while Tull got the larger studio, which was the main body of a converted church. The orchestral segments were arranged by Dee Palmer, who had worked with the band since 1968's This Was, and would later join as a keyboard player. The master reels were assembled at Apple Studios on 2 March 1971. Aqualung would be the last Jethro Tull album to include Clive Bunker as a band member, as he retired shortly after recording to start a family.
Musical style
The songs on the album encompass a variety of musical genres, with elements of folk, blues, psychedelia, and hard rock. The "riff-heavy" nature of tracks such as "Locomotive Breath", "Hymn 43" and "Wind Up" is regarded as a factor in the band's increased success after the release of the album, with Jethro Tull becoming "a major arena act" and a "fixture on FM radio" according to AllMusic. In a stylistic departure from Jethro Tull's earlier albums, many of Aqualung'''s songs are acoustic. "Cheap Day Return", "Wond'ring Aloud" and "Slipstream" are short, completely acoustic "bridges", and "Mother Goose" is also mostly acoustic. Anderson claims his main inspirations for writing the album were Roy Harper and Bert Jansch.
ThemesAqualung has widely been 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". Academic discussions of the nature of concept albums have frequently listed Aqualung amongst their number.
The initial idea for the album was sparked by some photographs that Anderson's wife Jennie took of homeless people on the Thames Embankment. The appearance of one man in particular caught the interest of the couple, who together wrote the title song "Aqualung". The first side of the LP, titled Aqualung, contains several character sketches, including the character of the title track, and the schoolgirl prostitute Cross-Eyed Mary, as well as two autobiographical tracks, including "Cheap Day Return", written by Anderson after a visit to his critically ill father.
