James Blake and Justin Vernon teamed up for “Fall Creek Boys Choir” five years ago. The two seem to be set to reunited and they are bringing the collaboration to the live setting.

Fans who purchased the early-bird tickets to Vernon’s second annual Eaux Claires Music & Arts Festival have also received a cassette tape containing b-sides, demos, and home recordings from a few of the acts on this year’s lineup. One track is attributed to Fall Creek Boys Choir.

Eaux Claires will take place August 12th – 13th in Eau Claire, Wisconsin. The cassette tapes seem to show that Vernon will play three separate sets during the festival weekend; in addition to Fall Creek Boys Choir, he will lead Bon Iver and perform alongside The National’s Aaron Dessner.

Other artists that are expected to appear at the festival: Bruce Hornsby, Jon Hopkins, Shabazz Palaces, Nathaniel Rateliff & The Night Sweats, and Arcade Fire members Richard Reed Parry and Sarah Neufeld, the latter of will perform with Colin Stetson.
