Exciting times lie ahead for one of our long-time fave bands, Bon Iver. Leader Justin Vernon recently announced that Bon Iver is back working on new songs for a new album. In addition, they recently completed an Asian tour and head to Australia in May, before performing this summer at Vernon’s now-annual Eaux Claires Music Festival. Bon Iver was/is backed on this tour by all three sisters of British group The Staves (Vernon produced their fantastic 2015 album If I Was). Today The Staves revealed a video of themselves, Vernon and Bon Iver warming up by warbling Flume before a show in a Hong Kong stairwell. Check out the harmonies and hi-jinx in the video below. Oh how these sisters can sing (not to mention Vernon’s fantastic falsetto). Long live Bon Iver!
