James Blake and Bon Iver’s Justin Vernon are preparing to perform live together under the moniker Fall Creek Boys Choir for the first time in five years.

Vernon and the National’s Aaron Dessner are bringing back Eaux Claires Music & Arts Festival to Wisconsin on Aug. 12 – Aug. 13. Those in possession of early bird tickets got sent a cassette tape teasing the festival’s line-up this year through a tracklist that organizers confirmed. A new Fall Creek Boys Choir song titled “Untitled 2” was listed. Other highlights include Bon Iver’s “Haven, Mass (B-Side),” as well as collaborations with Iver, Vernon, Dessner and his twin brother Bryce Dessner, who is also a member of the National.

Although the official website states the 2016 line-up will be announced soon, you can check out a pic of the tracklist below.
