Slate reports that Inherent Vice, Paul Thomas Anderson’s new film that was scored by Radiohead guitarist Jonny Greenwood, contains an unreleased Radiohead instrumental called “Spooks,” which the band began playing live during the In Rainbows era. The film, which is narrated by Joanna Newsom’s character Sortilège, was screened this weekend at the New York Film Festival ahead of its theatrical release on 12/12. Watch a video of Radiohead playing “Spooks” at a show in 2006 below.

UPDATE: Jonny Greenwood tweeted that the “Spooks” used in the movie is not exactly a Radiohead song. Rather, Greenwood re-wrote “Spooks” and recorded it with two-thirds of Supergrass (who are broken up).

@pitchfork except it's really a half idea we never made work live. I rewrote it and got supergrass to play it. It's good, but not very rh!

@doompeanut @pitchfork …yes, on one track. And in fact only 2/3 supergrass, so even that correction wasn't correct.
