The soundtrack for recent documentary 'Montage Of Heck', the album is billed as being released on the same day as the DVD release of the biopic - November 6th.
Billboard reports that director Brett Morgen was permitted access to an archive of unreleased material, which will form the spine of the new release.
Morgen previously told Stateside titled Bedford + Bowery: "Just to be clear, it’s not a Nirvana album, it’s just Kurt and you’re going to hear him do things you never expected to come out of him".
The material seemingly ranges "from thrash to ragtime and everything in between", and it will also include "a sketch comedy routine".
Reflecting on the full soundtrack, Morgen said: "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."
