The inaugural weekend of the Eaux Claires Music & Arts Festival in Eaux Claires, Wis., started off with a bang, hosting the National, who brought fellow indie greats Justin Vernon of Bon Iver and Sufjan Stevens on stage for a few songs. Check out some fan-recorded footage below.

Among other songs, Vernon and Stevens joined the group on stage for a cover of the Grateful Dead's "Peggy-O." At the same festival during their set, Bon Iver, who released their last album in 2011 and currently have an uncertain future, debuted two new songs live.

Vernon has collaborated on stage with the National many times over the past few years, including at Primavera Sound 2014. Stevens has also joined the National live several times, like last November at the O2 Arena in London. Stevens, The National and others also recently joined forces for a collaborative live album, One Night Only.
