WarChild was Jethro Tull’s last great album, a return to songs after the band’s segue into overblown opuses. The 40th Anniversary Theatre Edition includes stereo mixes of the original LP plus a glut of additional material, including previously unreleased tracks from the 1974 era (some of them interesting) and orchestral pieces intended for a never-made WarChild film. The 80-page illustrated booklet includes commentary by the always-witty Ian Anderson, who looks back on his arty youthful ambitions with a dismissive shrug.
