Radiohead, who titled their ninth studio album A Moon Shaped Pool, have a unique grasp on how easily profundity can slip into banality. Their music is obsessed with the point where great truths harden into platitudes, where pure signal meets wretched noise. In the past, Thom Yorke has sharply peppered his lyrics with everyday cliches to suggest a mind consumed by meaningless data, but on the new album, he largely moves beyond cynicism. He is now considering simpler truths in a heretofore-unexplored register: wonder and amazement. “This goes beyond me, beyond you,” he sings on “Daydreaming.” “We are just happy to serve you.” There is no concealed razor under Yorke’s tongue as he offers this thought, or in the pearly music that surrounds him. It sounds for all the world like the most cloistered and isolated soul in modern rock music opening up and admitting a helplessness far more personal than he’s ever dared. Yorke has flirted with surrender before, and on A Moon Shaped Pool, that submission feels nearly complete.
