Justin Vernon and Aaron Dessner's annual Eaux Claires festival puts a lot of focus on collaborations between artists, and the 2018 edition, which wrapped up on Saturday (7/7), was no different. One of the mysterious items on the schedule, which was released only at the beginning of the festival's first day, was the "Eaux Claires Women's Choir." This wound up being a collaboration between Julien Baker, Phoebe Bridgers, Anais Mitchell, Channy Leaneagh (of Polica), Kristín Anna Valtýsdóttir (formerly of múm), and Gordi. They joined forces for some covers, including Antony and the Johnson's "Another World," and Carter Family's "Keep on the Sunny Side." Watch video clips of both songs below.

As Stereogum points out, later on in the day the sextet covered Gillian Welch's "Everything is Free" during the PEOPLE Mix Tape set. Watch that below, as well.

Julien and Phoebe also joined The National for their Saturday night set at the festival.
