As many predicted (and hoped) they would, Radiohead has released a new song, "Burn the Witch." The song finds the band back in song mode, mixing acoustic instruments and an electronic beat while a restrained but insistent string section provides a nervy, increasingly frantic accompaniment to a classically paranoid lyric about messenger shooting, mob rule, and alienation and one of those indelible Thom Yorke head voice melodies. I've only listened to it like 10 times in the last 45 minutes, but so far I'd say "Burn the Witch" is exactly what you want from Radiohead in an election year. (And the video is The Wicker Man meets Davey and Goliath, which is to say A+++.)
