Two years after airing Brett Morgen’s Rolling Stones documentary, Crossfire Hurricane, HBO has signed up to air his long-simmering documentary on Kurt Cobain. 
  
 The Nirvana frontman died in 1994 at the age of 27 and has been the subject of many books and films since, including other documentaries like 1998’s Kurt & Courtney and 2006’s Kurt Cobain: About a Son. 
  
 Morgen’s been working on his documentary, Kurt Cobain: Montage of Heck, for over five years and says he hopes the film will show Cobain fans that the man wasn’t only the face of Nirvana. 
  
 “The thing about him people might not know too is that he was an incredible visual artist and left behind a treasure chest of comic books, paintings, Super 8 films, all sorts,” Morgen told Fact in 2013. “We are going to do the movie sort of like a third-person autobiography, as if Kurt was around and making a film about his life.” 
  
 Frances Bean Cobain, Cobain and Courtney Love’s daughter, is executive producing. The film will debut on HBO and Universal will release the film internationally in 2015. ||||| An unseen image of Kurt Cobain at home, featured in the film Kurt Cobain: Montage of Heck, © The End of Music, LLC/courtesy HBO 
  
 HBO has announced that filmmaker Brett Morgen's Kurt Cobain documentary Montage of Heck will premiere on the premium cable channel next year. Though Montage of Heck is the latest in a long line of Nirvana/Cobain films—most notably, AJ Schnack and Michael Azerrad's About a Son—the film is being billed as the first "fully authorized" one. It was made with participation from Kurt Cobain's family. In fact, Frances Bean Cobain, Cobain's daughter with Courtney Love, is attached as executive producer. (There is no mention of Love in the press release, however.) 
  
 Montage of Heck takes its name from a mixtape Cobain made in the late 80s. The documentary features "dozens of Nirvana songs and performances as well as previously unheard Cobain originals," according to a press release, in addition to "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." 
  
 In the press release, Morgen said: 
  
 I started work on this project eight years ago. 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 (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. 
  
 HBO currently airs the miniseries Sonic Highways, directed by Cobain's former bandmate Dave Grohl.

A new documentary about Kurt Cobain will debut next year on HBO, and this one has a twist—the singer's daughter, Frances Bean Cobain, will be executive producer, reports Entertainment Weekly. The documentary by Brett Morgen is billed as the first film about Cobain authorized by his family, though Pitchfork notes that the press release makes no mention of widow Courtney Love. Morgen says the documentary will make clear that Cobain was not just a singer but a talented "visual artist." The title will be Montage of Heck, a name Cobain himself gave to a mix tape he made at age 21.
