Bon Iver returned to Late Night with Jimmy Fallon last night to play "Holocene," a beautiful, densely arranged ballad from their hot new album Bon Iver. ?uestlove, who has seen hundreds of artists perform on the show since his the Roots became the show's house band two years ago, was particularly impressed by the song. After the taping yesterday, the drummer tweeted "'Holocene' might be the most beautiful moment on @latenightjimmy. i think i just grew some wings." High praise indeed!
