The project Anonymous Content director Brett Morgen has been working on for the last 8 years has been officially announced. Gen Xers everywhere now anxiously await the premiere of Montage of Heck, the first fully authorized feature documentary about iconic Nirvana frontman, Kurt Cobain.

The no-holds-barred portrait, slated to premiere on HBO in 2015, is the first documentary to be made with the cooperation of Kurt Cobain’s family, with his daughter, Frances Bean Cobain, serving as the film’s EP. (She recently tweeted: “I’m really excited for you guys to see Montage of Heck. @brettmorgen created an intense yet wonderful examination of Kurt’s life & art.”)

“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.”
