While at Lollapalooza Brazil, Band of Horses played a surprise acoustic set just inside the gates of the festival. The set included a few Band of Horses staples as well as a new song the group is working on for their next studio album. The performance was captured on video and has since turned up—with the title misidentified as “Long Vows.” A statement from the band confirms the song is still currently untitled.

This is the first song the group has played from their next album. Band of Horses are currently working on a new studio album with Rock and Roll Hall of Fame inductee Glyn Johns (The Beatles, The Clash). The album will feature the band’s current lineup: Ben Bridwell, Creighton Barrett, Ryan Monroe, Bill Reynolds and Tyler Ramsey.
