On Friday night, Bon Iver opened the Eaux Claires Music Festival by debuting their new album in full. Last night there was an equally special closing during Francis and the Lights' set.  To help the band perform "Friends," both Bon Iver and Chance The Rapper came out as surprise guests. The group also performed Chance's Coloring Book track “Summer Friends.” Most impressive though? They whipped out some choreographed dance moves (which you can see in the last video below.)

During the set, Francis and the Lights also announced their new album, which will reportedly be called Farewell Starlite.

Watch footage of the performances below.
