Phoebe Bridgers is already pals with Ryan Adams and Conor Oberst, and it seems she’s added Justin Vernon to that list. Bon Iver just finished up an eight-night residency at London’s Eventim Apollo last night, and after opening the show, Brooklyn Vegan reports that Bridgers also joined the band onstage to sing “Flume.” Watch their onstage collaboration below.
