The first fully-authorized documentary about the late Kurt Cobain, entitled Kurt Cobain: Montage of Heck, will debut on HBO in 2015 in the United States.

The documentary was directed by Oscar nominee Brett Morgen, whom the New York Times has referred to as the “mad scientist” of documentary filmmaking. Kurt Cobain’s daughter, Frances Bean Cobain, is executive producer of the project. HBO Documentary Films and Universal Pictures International Entertainment Content Group are co-producing the film, which is slated for international release. There are a lot of fans who have surely been awaiting a look into the mind of Nirvana’s lead guitarist, vocalist and songwriter – an icon in grunge and in music history.

As the first Cobain documentary to be made with the family’s full cooperation, it will contain never-before-seen home movies, recordings, artwork, photography, journals, demos, personal archives, family archives and songbooks. There will also be numerous Nirvana songs and performances, as well as Cobain songs that have gone previously unheard.

“I started work on this project eight years ago,” says Morgen. “Like most people, when I started, I figured there would be limited amounts of fresh material to unearth. However, once I stepped into Kurt’s archive, I discovered over 200 hours of unreleased music and audio, a vast array of art projects, countless hours of never-before-seen home movies, and over 4000 pages of writings that together help paint an intimate portrait of an artist who rarely revealed himself to the media.”
