Today is an exciting day for Bon Iver fans, because a previously unreleased track from the master of ethereal folk has just surfaced. The song, titled "Haven, Mass", appears on a cassette tape that's been sent out to those who purchased early tickets for his upcoming Eaux Claires Music & Arts Festival in Wisconsin, and, though we aren't sure if it's indicative of more music from him to come, any new material from Iver has proven to be something to cherish. You'll want to listen to this one below.
