The legacy of grunge band Nirvana and its late frontman, Kurt Cobain, is still very much alive. In fact, it is even growing. In November a collection of demos and home recordings made by Cobain will be featured on the soundtrack for "Kurt Cobain – Montage of Heck," Brett Morgen's documentary about the late rock star which hit theaters in April. The previously unreleased material should be a gold mine for fans looking to dig a little deeper into Cobain's career. 

According to Rolling Stone, "Kurt Cobain – Montage of Heck: The Home Recordings" will be released on Nov. 13. The album will feature many raw cassette recordings Cobain made while alone in his home throughout the early years of his career. The snippets include material that would later be converted into many of Nirvana's most well known hits. The album will be available digitally, as a 13-song CD, and on vinyl as a 31-track deluxe album.

The soundtrack, of course, accompanies the film, "Kurt Cobain – Montage of Heck." The movie chronicles the musician's troubled childhood and meteoric rise to fame as the frontman of Nirvana, plus Cobain's drug-fueled marriage to fellow rock star Courtney Love. The critically acclaimed documentary uses rare home videos, audio recordings, journal entries, and art to tell Cobain's story. "Montage of Heck," which is currently available on HBO GO and HBO Now, will be released on DVD the same day as the soundtrack release. 

Director Brett Morgen tweeted Monday to tease the film's music buff-ready soundtrack, touting the never-before-heard material the film's producers gained access to in production of his documentary.

What will the home recordings reveal for devout Cobain fans? Only time will tell. The "Montage of Heck" soundtrack will be released on Nov. 13, just in time to make the perfect holiday gift for any grunge fans in the family.
