An album of unreleased music from the Nirvana frontman will be released in November. 

Brett Morgen’s Kurt Cobain documentary Montage of Heck hits theatres on November 6. To coincide with the film’s release, Universal Music will deliver an album of unreleased music from the iconic rocker. Director Brett Morgen has confirmed the as-yet-untitled LP will arrive on the same day as the documentary.

According to Morgen, the album will contain all of the music featured in the documentary along with a dozen additional tracks, “audio montages” and even a comedy sketch. Morgen curated the material after sifting through “hours upon hours” of Cobain’s personal archives.

“[It’s] curated to feel as though one were sitting in Kurt’s living room watching him create over the course of an afternoon,” Morgen told Billboard. The songs range “from thrash to ragtime and everything in between.”

“These are all just Kurt by himself with the guitar,” Morgen added. “These aren’t multi-track, finished songs or work-ups, but they’re extraordinary, and I think they provide a tremendous insight into his [creative] process. I think they further our understanding of Kurt, both as a musician and as a man.”

Melvins frontman Buzz Osborne, friend and mentor of Cobain, says Montage of Heck is “90% bullshit.” [via CoS]
