Watch New Clip From KURT COBAIN Documentary 'Montage Of Heck'

The Guardian has uploaded a new clip from the forthcoming Kurt Cobain documentary "Montage Of Heck". In this clip, Cobain's diaries reveal some of the names NIRVANA toyed with before deciding on the moniker they'd use to define a musical era.

"Montage Of Heck", the first documentary about Cobain made with the authorization and cooperation of his family, premiered at the Sundance Film Festival in Park City, Utah on January 24. According to The Pulse Of Radio, the film was praised in several reviews, with The Wrap calling it a "bold, generous portrait of a man who was clearly a tortured teenager before he was a tortured artist and a reluctant icon," adding that parts of the two-hour-plus film were "shockingly personal."

Badass Digest was more detailed in its review, noting that the film was "as much a tour of Kurt's mind as it is a retelling of his life," and revealing that it includes photos and recordings of Cobain and Courtney Love having sex among its more intimate materials.

The film relies less on straight documentary reporting and is constructed more like a collage of previously unseen home movies, interviews, animation, photographs and other artifacts, all accompanied by Cobain's music.

Kurt's daughter, Frances Bean Cobain, is an executive producer on the film. She, Courtney Love, Kurt's parents and NIRVANA bassist Krist Novoselic all appear in the movie.

DirectorBrett Morgen was asked at the premiere why NIRVANA drummer and FOO FIGHTERS frontman Dave Grohl did not appear in his film. Morgen explained that Grohl was interviewed but that there was not enough time to edit his segment into the movie before the Sundance screening.

"Montage Of Heck" will be shown in theaters in Los Angeles, New York and Seattle starting on April 24. It will be shown in 72 countries, beginning April 10, prior to its May 4 debut on HBO. A DVD release is scheduled for November.
