Bon Iver’s Justin Vernon has already promised a set of new music for the band’s August performance at his Eaux Claires Music Festival, but the indie folk frontman seems to be hinting at a larger-scale release in a cryptic new video.

Posted to the group’s official Facebook page Thursday, the 20-second clip centers on a laptop screen flashing through a series of abstract images. It also features what could be new music — a droning, choral-inflected cut — from Bon Iver, who haven’t released an album in over five years. The band also updated their website, profile, and cover photos with snapshots culled from the video.

The caption, which reads #22days, coincides with the second and final night of Eaux Claires. Vernon co-founded the festival with the National’s Aaron Dessner in 2015.

Bon Iver last released 2011’s Bon Iver, their Grammy Award-winning second record. Vernon later stated they were “winding it down” for an extended break. Last February, the group picked back up with a string of concerts in Asia and Australia, and Vernon told Billboard he was “definitely” working on new music.

Bon Iver are currently set to play a short set of West Coast shows, including dates with Francis and the Lights and a one-off stop with Patti Smith. Watch their mysterious video below.
