Following quickly on the heels of their career-defining Aqualung and Thick as a Brick, Ian Anderson's Jethro Tull demonstrated that their musical and thematic ambitions were as muscular as ever on 1973's Passion Play. But if Thick was a bit tongue in cheek about its conceptual conceits, Passion was a dizzying example of the prog-rock era's overweening musical aspirations at their zenith. Anderson now sums up it its obtuse, theater-as-metaphor libretto as "the theme of post-death meanderings in another world," but the sheer propulsive tension of Tull's sprawling musical interplay insures its folk-rooted baroque and roll a tight orbit around this mortal coil for nearly the album's entirety. This digitally remastered, enhanced CD edition features the complete video for the album's Lewis Carroll-esque interlude "The Hare Who Lost His Spectacles," a theatrical program and typically self-effacing new introduction by Ian Anderson. --Jerry McCulley
