Bon Iver’s Justin Vernon and James Blake are set to perform live under the name of their first recorded song in 2011, Fall Creek Boys Choir. The performance, which will see the pair reunite after a long break, are set to perform at Wisconsin’s Eaux Claires Music & Arts Festival on August 12th and 13th.

Although the official lineup is yet to be announced, festivalgoers who bought early bird tickets were sent a cassette tape with a track list teasing this year’s lineup. Consequence of Sound reports that the cassette tapes contain b-sides, demos, and home recordings of some of the acts scheduled to perform, as well as a track list teaser.

Included in the teaser is a song titled “Untitled 2” by Fall Creek Boys Choir. Justin Vernon is also set to play “Haven, Mass (B-Side)” with his band Bon Iver and share the stage with The National’s Aaron Dessner. 

Eaux Claires' official lineup is scheduled for release on February 11th.
