Ian Anderson reflects on Jethro Tull’s long career in an unusually candid question-and-answer session led by fellow progressive-rock musicians, collaborators and admirers. The interview matters as it presents the 78-year-old bandleader’s perspective on the group’s continuing activity, their legacy and encounters with peers from across the genre.

Anderson formed Jethro Tull in London in 1967, and the band is approaching its 60th anniversary while still touring and releasing new music. Tull have issued three studio albums in four years and are continuing an archival reissue campaign, most recently reaching 1984’s Under Wraps; Anderson also recalls John Lydon enthusiastically praising Aqualung after drinking several beers.
