Sufjan Stevens has been working on a bunch of surprises. Not only has the singer-songerwriter released a brand new concert film from his tour supporting his 2015 album Carrie & Lowell, but he has also announced a new mixtape to accompany the project.

The film spans an hour-and-a-half, and includes footage from his performance at the North Charleston Performing Arts Center. While it features a ton of acclaimed music, Stevens will release his new mixtape titled The Greatest Gift Mixtape — Outtakes, Remixes, & Demos from Carrie & Lowell, featuring unheard material on October 20.
