According to The Pulse Of Radio, a previously unheard demo recording by late NIRVANA frontman Kurt Cobain will turn up on the soundtrack of the documentary "Kurt Cobain: Montage Of Heck" when it is released in theaters next Friday (August 7). Director Brett Morgen told Billboard that he added the song, which features Cobain singing in a falsetto, to the movie without having to make any changes to the film. "Montage Of Heck" had a brief theatrical run last spring before premiering on HBO in May.
Morgen did not want to say where in the film the song appears, explaining, "I don't want to get people out there bootlegging it on their cell phones."
The track, like many of the songs used for the movie from the cassettes in Cobain's personal archive, does not have a title, although it might have been recorded in 1991.
Although "Montage Of Heck" played on HBO and has been nominated for seven Emmy Awards, Morgen said it was "built as a theatrical experience, so we decided we would bring the film back into theaters."
Morgen built the movie around recordings taken from 107 cassettes that Cobain recorded over a period of many years, equaling around 200 hours of audio, as well as previously unseen artwork by the singer/guitarist.
Morgen told The Pulse Of Radio that he could not believe how much material Cobain created in his relatively short life. "I'd never met anyone who was as prolific as he was," he said. "I mean, given his short life span and that a lot of that time, he didn't have a secure home, the amount of materials that we have present a guy who just never stopped creating, and that is beyond inspirational."
Morgen was given complete access to Cobain's personal archives by his widow Courtney Love and daughter Frances Bean Cobain.
