Justin Vernon has said that he's been working on new music for Bon Iver. Today (July 22), we may have just gotten our first peek at what's in store.

Bon Iver posted the above video to its social media feeds with the hashtag "#22days." In its 22 seconds, you hear some keyboard blips and vocals that sound like they've been treated with all sorts of effects. The clip ends just as what could be Vernon's falsetto enters the picture.

It's probably not a coincidence to note that, in 22 days, they will be playing a set at their own Eaux Claires Music and Arts Festival in Eau Claire, Wisc., their hometown. Last month, Vernon promised to perform an entire set of all-new music at the festival, which will also include sets by Mavis Staples, Lucius and Nathaniel Rateliff & the Night Sweats.

Three unreleased songs, “Creature Fear,” “Michicant” and “Heavenly Father,” were premiered during Bon Iver's four-night stand at the Sydney Opera House back in May. Vernon also collaborated earlier this year with James Blake on "I Need a Forest Fire." The track appeared on Blake's The Colour in Anything.

Still, they have not released an album since 2011's Bon Iver, Bon Iver, which debuted at No. 2 on the Billboard 200. It also won Grammys for Best Alternative Music Album and, even though it was their second record, Best New Artist.

Two months after the Eaux Claires festival, Bon Iver will play four shows in California, including a night at the prestigious Hollywood Bowl on Oct. 23. Patti Smith will serve as the opening act.
