HBO have announced they will be airing the first ever 'authorised' documentary on late Nirvana frontman Kurt Cobain. Entitled ‘Kurt Cobain: Montage of Heck’, the film has been directed and produced by Brett Morgen, who previously followed The Rolling Stones for ‘Crossfire Hurricane’ in 2012.

The doc is thought to be premiering on HBO some time next year, while Universal Pictures Intl. Entertainment will distribute it as a theatrical release and to TV outlets in markets outside the U.S.

During the filming of ‘Montage of Heck’ Morgen was granted ‘unprecedented access' to Cobain's archives, including never-before-seen home movies, recordings, artwork, photography, journals, demos and songbooks. The film will also include songs and performances from Nirvana, as well as previously unheard Cobain originals.

“Like most people, when I started, I figured there would be limited amounts of fresh material to unearth,” Morgen said in a press release. “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.”

Since his death at the age of 27 in April 1994, Cobain has gone on to be remembered as the voice of a generation and is credited with popularising Seattle’s grunge movement. Earlier this year Cobain was posthumously inducted into the Rock and Roll Hall of Fame along with his Nirvana bandmates Krist Novoselic and Dave Grohl.
