Bon Iver’s Justin Vernon and the National’s Aaron Dessner are kicking off their inaugural Eaux Claires Festival on 7/17 and 7/18 in Eau Claire, Wisconsin. The National and Bon Iver are both headlining, of course, along with Spoon and Sufjan Stevens. The Tallest Man On Earth, Hiss Golden Messenger, and 34 other artists will also be performing. Yesterday, they just released a digital version of a festival guide (which will be distributed in physical form to everyone who attends) based on Vernon’s field notes, including a pronunciation guide (“Bon Iver: No idea,” band bios and logos designed by Vernon, and, naturally, moon phases. You can check it out here, and in a blog post on the Eaux Claires website, festival creative director Michael Brown describes the story behind it:

Months ago, as we were conceptualizing and brainstorming the different aspects of this festival, Justin would scribble his thoughts and ideas in a series of Field Notes. (If you’re not familiar with Field Notes, they’re small, pocket-sized journals, intended to be always at hand in the event you need to “notate” in the moment. Their distinctive appearance is the work of Draplin Design—who, by the way, worked with Justin and I to create the Eaux Claires logo. (Thanks, Draplin!)

After scribbling his way through several of these mighty little notebooks over the course of those incubation sessions, Justin felt compelled—then INSISTED—that everyone coming to this festival should have something similar. Something tangible that acts as a keepsake, guide, portal, and record of their experience at the festival. And so began an attempt to fashion a simple journal to make sure every festival attendee could walk away with something to remember the summer.
