Yesterday, Bon Iver teased what looked like a newspaper to accompany their upcoming album 22, A Million (out September 30 via Jagjaguwar). In addition, they announced a string of mysterious events in Brooklyn, Paris, Los Angeles, and more cities. The first of those events took place last night in Justin Vernon’s hometown of Eau Claire, Wisconsin. At the event, which took place in front of a 22, A Million mural, fans gathered to listen to Bon Iver’s new record on a boombox, according to WEAU. They also received the newspapers, which Bon Iver have said are limited to three per person. The band have also advised fans at the events to “flip the tape” when each side of the cassette stops. Currently, Bon Iver’s London event is taking place; see the rest of the cities here. Check out photos and footage from the Eau Claire premiere below.

In addition to the Eau Claire listening event, Justin Vernon played a surprise show in Berlin last night. He’s in the city for a massive event that he organized along with the National’s Aaron and Bryce Dessner, Gayngs’ Ryan Olson, director Vincent Moon, conductor André De Ridder, Brandon Reid, and Berlin’s Michelberger Hotel. The performers are working and rehearsing ahead of the October 1 and 2 two-day event. Below, see artists rehearse a cover of David Bowie’s “Space Oddity.” Also, see Vernon practice 22, A Million’s “10 d E A T h b R E a s T ⊠ ⊠,” as well as an introductory video for the event.
