Sufjan Stevens has released a new song called "Wallowa Lake Monster."

The seven-minute track, which arrived Wednesday, is a preview of Stevens' upcoming project The Greatest Gift Mixtape, which is out on Oct. 20 and said to be a companion to his 2015 album Carrie & Lowell. It is made up of outtakes, remixes and demos from that album.

The new music follows Stevens' recent Carrie & Lowell Live album and his collaborative Planetarium album. He has also contributed to the soundtrack for Luca Guadagnino’s film Call Me By Your Name, which is out on Nov. 24, with the soundtrack arriving Oct. 27.
