During a Coachella weekend that was all about surprises, Bon Iver’s JUSTIN VERNON joined POLIÇA onstage to perform a new song titled “Tiff”. Below is the studio version of the Minneapolis quintet’s new single and like you’d expect – given 2012’s Give You The Ghost and, well, Justin Vernon – it bleeps and bloops with some serious blues. To cure that Monday hangover, make sure to watch the group perform “Amongster” and “Wandering Star” in Indio.
