After sharing two new studio tracks a month ago, Bon Iver have now teased an upcoming project with a trailer titled “Sincerity is Forever in Season.”

The video features various images from nature with a voiceover that traces Justin Vernon’s album output as Bon Iver through the lens of passing seasons, as tracks from each of his albums, 2007’s For Emma, Forever Ago, 2011’s Bon Iver and 2016’s 22, A Million.

“And now, it might be autumn,” the voiceover says over a snippet of “Hey Ma,” one of Bon Iver’s new tracks, hinting that the trailer is pointing toward an upcoming studio effort. The final frames of the video also list several of Vernon’s frequent collaborators—counting Chris Messina, Brad Cook and Vernon as producers—before a final trailer card that reads, “Bon Iver Coming Soon” (along with a mysterious tagline, “Keep it Restaurant”).

Watch below, and stay tuned for more information on the upcoming project.
