Update 8/13/15: Montage of Heck director Brett Morgen has confirmed that the album will hit stores November 6 and will be packaged as a soundtrack to the documentary, which will also become available on DVD that day.

The new Kurt Cobain documentary Montage of Heck is among the most enthralling and stomach-churning rock docs ever made. It's more intimate than I Am Trying to Break Your Heart, more personal than Don't Look Back, and the bevy of performance footage—from leaky basements to mega-festivals to MTV Unplugged—rivals the intensity of The Song Remains the Same or the emotion of The Last Waltz. Cobain's home movies, journals, doodles, paintings, and amateur audio recordings piece together the story of a brilliant, lonely, horny, anxious, ambitious, rejection-fearing mind. One minute Cobain is screaming and shrieking before tens of thousands of fans, the next he's mumbling his way through basic conversation with a shame-filled vocal fry. It's not an easy film to watch. Director Brett Morgen brings you so close to Cobain that he almost feels like a friend of a friend by the time it's over. And much of that is because of the constant presence of Cobain's voice.

Now, Morgen has revealed that the cassette tapes, home recordings, and other archival material will come together and be released as a new Kurt Cobain album. No, this is not a Nirvana record. As Morgen told the New York blog Bedford and Bowery, the record "will feel like you're kind of hanging out with Kurt Cobain on a hot summer day in Olympia, Washington, as he fiddles about. It's going to really surprise people."

In his quest to make the film, Morgen was granted full access to Cobain's storage unit after "several years of legal situations" following a meeting with Courtney Love in 2007. And once inside, he found more than he could have imagined.

As Morgen describes it in the interview:

"Well, I entered into a non-descript industrial storage room with industrial lights and carpet and low ceilings ... And in the middle were maybe a dozen boxes that felt quite small within the space. I remember thinking as I gazed upon this, 'What did I just get myself into? Where is all this stuff?'

"I go and open a box and out comes a big collection of videotapes ... And then I opened up another box and there were 107 cassettes featuring over 200 hours of never-before-heard or rarely heard music — I mean I would lean heavily of the never-before-heard, probably 95 percent.

"The audio ran the gamut from jam sessions with Courtney, some jam sessions with various friends and Nirvana, his first demo tapes, his Fecal Matter demos, his mix tapes and oral canvases like Montage, a lot of silly spoken word stuff and not-silly spoken word stuff like the story he told of losing his virginity, covers of the Beatles songs, it just ran the gamut."

Posthumous releases are always tricky. While unearthed material is forever intriguing to fans, some consider it offensive to cobble together a record of an artist's work without their consent or input on basic things like pacing and track order. Sometimes they work: Jimi Blues, a mix of Jimi Hendrix originals and his interpretations of blues standards, was released in 1994 and remains one of the most listenable albums in the sprawling Hendrix catalogue (alongside other posthumous releases). Hendrix's guitar work on "Born Under a Bad Sign," a blues cover, is as brilliant as anything he does on "Red House" or "Voodoo Chile." We're lucky Jimi Blues exists. Hendrix, of course, shares Cobain's Pacific Northwest roots and also died at age 27.

But sometimes, these sort of releases feel cheap. As made clear by the documentary, Cobain was obsessive about every detail of Nirvana's "brand." Bassist Krist Novoselic explicitly says that Cobain had a mixture of fear and rage surrounding the larger idea of being poorly-perceived by the media or general public. If Cobain were alive today, would he ever sign off on a release of rough demos and covers? Cobain's lo-fi acoustic cover of the Beatles classic "And I Love Her" recently made its way around the web, and should be an indication of what's to come on the new record this summer.
