Dirty Projectors hit the Late Show With David Letterman last night to performing the title track from their new EP, About to Die. Singer and guitarist David Longstreth and his bandmates ably navigated the twists and turns of the knotty song, with swirls of female harmony vocals surrounding Longstreth's lead parts while a small string section helped fill out the sound. And then – no joke – a shirtless guy accompanied Letterman as he greeted the band at the end.
