Roger Daltrey sounds half a century younger than his seventy-five years on the amazing comeback “Who” album, full of vinegar and still soaring. Pete Townshend’s songs, mostly about old rockers shouting and pondering but with 2019 checkpoints, are sprightly and varied, another surprise (most old songwriters have lost their mojos). His guitar sounds as sharp as ever. The anthemic, churning “All This Music Must Fade” is a hoot, “Beads on One String” does hippy lyrics proud, and “Street Song” rages about the Grenfell building disaster. A couple of lame tracks cannot dampen the renaissance.
