HBO is teaming with Oscar nominated documentary filmmaker Brett Morgan for Kurt Cobain: Montage of Heck, the first authorized documentary on the late Nirvana frontman. Cobain’s daughter, Frances Bean Cobain, is also onboard as an executive producer.

Montage of Heck is a co-production between HBO Documentary Films and Universal Pictures International Content Group. The film will debut in 2015 and will air exclusively on HBO, the network announced Tuesday.

Cobain died at age 27 in 1994, at the height of Nirvana’s popularity. His life and music remain a major part of pop culture, with fans hungry for a real portrait of the artist. Morgen hopes to give it to them.

Morgen said that he began working on the film eight years ago.

“Like most people, when I started, I figured there would be limited amounts of fresh material to unearth,” Morgen said. “However, once I stepped into Kurt’s archive, I discovered over 200 hours of unreleased music and audio, a vast array of art projects (oil paintings, sculptures), 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.”

Montage of Heck will feature never-before-seen home movies, recordings, artwork, photography and his writings. Several Nirvana songs will be featured, as well as unheard Cobain originals.

Morgen was nominated for an Oscar in 2000 for On The Ropes. His other films include The Kid Stays in the Picture and HBO’s Rolling Stones documentary, Crossfire Hurricane.
