The posthumous album of Kurt Cobain is set to come out in November of this year to accompany the release of a DVD documentary on the late Nirvana frontman.

Brett Morgen, the filmmaker of the documentary, found more than 100 early cassette tapes that were recorded by the grunge icon while doing some research for "Montage of Heck."

Morgen revealed that the album will serve as a soundtrack to the documentary. Both the soundtrack and the DVD documentary will be available on Nov. 6, according to Yahoo! News.

The director also said that the album will contain "audio montages that Cobain created," as well as recordings of the artist talking in between tracks, including "a sketch comedy routine featuring Kurt voicing all of the characters."

Morgen described the songs as ranging "from thrash to ragtime and everything in between" but notes that: "Most of it is in a space that will be familiar to Nirvana fans," Billboard reported.

"You really get a sense of how happy he was simply by creating himself. His lyrics are really playful, and, at times, you can feel his smile and warmth coming through," Morgen said of the soundtrack in its entirety, according to Uncut.
