Bon Iver’s Justin Vernon and the National’s Aaron Dessner are bringing the Eaux Claires Music & Arts Festival back to Eau Claire, Wisconsin for its second year this summer. The lineup has yet to be officially announced, but they’ve just sent out a mixtape cassette featuring “b-sides, demos, home recordings, and spontaneous contributions” from artists on the lineup to fans who purchased early bird tickets to the fest.

The tracklist contains an untitled song by Fall Creek Boys Choir, the Justin Vernon/James Blake team-up that released one very pretty song back in 2011, which implies that Vernon and Blake will be performing together live for the first time at this year’s festival. We can also expect to see Bon Iver, Vernon and Dessner performing together, Bruce Hornsby, Arcade Fire’s Richard Reed Parry, Shabazz Palaces, Jon Hopkins, Nathaniel Rateliff, Sarah Neufeld, Colin Stetson, My Brightest Diamond, William Tyler, Tenement, Buke And Gase, and Phil Cook, among others.

The fest has also recently shared a teaser video showcasing a new location for camping. Watch that below.

The festival will take place 8/12-13 at Foster Farms outside of Eau Claire, Wisconsin.
