Aqualung is the forth album by Tull and many people think that it is their best. I favor Thick as a Brick, but it is still an excellent album. Rumor has it that critical comments about Aqualung spawned Thick as a Brick, and we shall discuss that in a bit.
It was released on 19710319 on Island Records in the UK and Reprise in the US. By this time Anderson had completely taken control of the band, and all of the songs are written by him except for the title track which was cowritten by his wife at the time, Jennie. Anderson, along with Terry Ellis, produced it.
The band lineup was different than that of Benefit, with Jeffrey Hammond replacing replacing Glen Cornick on bass and Barriemore Barlow replacing Clive Bunker on drums. Remember, Jethro Tull has had more personnel changes than many bands. Otherwise the lineup was the same as on Benefit.
