22, A Million is the third studio album by American indie folk band Bon Iver, released on September 30, 2016. It was recorded in Justin Vernon's April Base studio in Eau Claire, Wisconsin, and marked a shift in the band's sound, incorporating elements of electronic music and hip-hop production, and making extensive use of samples, synths, brass instruments, and effects. Vernon has stated that many of the sounds on the record were created and manipulated using a Teenage Engineering OP-1 synthesizer, along with software designed specially for the band by Chris Messina dubbed the "Messina". On August 28, 2016, all but one of the ten tracks were made available after an error occurred on Apple Music in Denmark. The single that was meant to be available, "33 "God"", was the only song unavailable, until the day after, when the album had officially leaked in full following the single's international release, barely over a month before its official release date of September 30. Even after it was taken down in Denmark, low quality mp3's and zip files began circulating on the internet.
