[citation needed] Past performers include Bon Iver, The National, Paul Simon, Chance the Rapper, Lizzo, the Indigo Girls, Wilco, Sufjan Stevens, Erykah Badu, Spoon, Blind Boys of Alabama, Sturgill Simpson, Doomtree, Vince Staples, Tenement and James Blake.
The second night was anchored by Sufjan Stevens followed by Bon Iver, who closed the festival playing songs from both of his albums along with many guest artists.
The Thursday night campground performances were replaced by a ticketed show in downtown Eau Claire by Phil Cook and the Guitarheels, who would also play the festival itself.
[citation needed] In early February 2017 the creative team announced an overhaul for the third iteration of the festival via a bound book named "Troix".
Additional changes included the uphill area no longer being used, a revamping and expansion of the forest trail stages, and minimal[clarification needed] schedule overlap between band sets.
[21] On November 15, 2017 the fourth edition of the festival was announced and tickets went on sale immediately, alongside a cryptic 29-minute audio file Please Listen #1 that included voice recordings and music clips.
[22] A second audio collection called Please Listen #2 was released alongside several Instagram posts with videos featuring discussions about The National and Sharon Van Etten performing.
[23][24] The organizers later revealed that there would be no "marketed lineup" for this fourth year of the festival,[25] though through his Twitter feed Justin declared many of the bands from the Please Listen podcasts as being highly likely,[26] while later making note that they've not "announced anything".
Additional acts included main stage sets from Wye Oak, Serengeti, Sharon Van Etten, Kevin Morby, Moses Sumney, Noname, Phoebe Bridgers, with acoustic performances from Hiss Golden Messenger, Dirty Projectors, and late night sets from Low, Mouse on Mars, and Marijuana Deathsquads.
