A preview of an unreleased demo by Kurt Cobain has surfaced in the a new clip for the upcoming documentary, Kurt Cobain: Montage of Heck

It’s only 38 seconds long, but you can hear the late Nirvana singer’s somber crooning swim around an acoustic guitar that sounds like it’s been sitting under a leaky roof for a year. Maybe that’s just the animation doing the talking, which is worthy of a viewing alone. The full version of the track will debut with the next issue of Rolling Stone, out this Friday.

In related news, the magazine interviewed Frances Cobain-Bean, who spoke for the first time about the project. She admitted that she “[doesn’t] really like Nirvana that much” because “the grunge scene is not what I’m interested in.” Instead, she referenced other artists like Mercury Rev and Oasis, though added this about her late father:

He’s larger than life. And our culture is obsessed with dead musicians. We love to put them on a pedestal. If Kurt had just been another guy who abandoned his family in the most awful way possible . . . But he wasn’t. He inspired people to put him on a pedestal, to become St. Kurt. He became even bigger after he died than he was when he was alive. You don’t think it could have gotten any bigger. But it did.”


You’ll see why in Brett Morgen’s definitive documentary, which features “no-holds-barred access to Kurt Cobain’s archives, home to his never-before-seen home movies, recordings, artwork, photography, journals, demos, personal archives, family archives and songbooks.”

The film hits select theaters this weekend and will air May 4th on HBO. The accompanying soundtrack, which still has no release date, is said to feature a previously unheard 12-minute acoustic track.
