A Passion Play

A Passion Play is the sixth studio album by Jethro Tull, released in 1973. Like its predecessor, Thick as a Brick, it is a concept album with a single song (which was split into two parts on the original vinyl LP release). The theme of the concept is apparently the spiritual journey of one man in the afterlife.
Upon its original release, it received generally negative reviews. Nevertheless, it sold well enough to reach #1 on the charts in the United States. In the United Kingdom it reached only #13
