Unreleased solo Cobain track coming with 'Montage of Heck'

If your cable or satellite provider is doing a special for a certain amount of months to grab HBO, I would recommend grabbing it in time for May as the HBO documentary Kurt Cobain: Montage of Heck is already drawing rave reviews on the film festival circuit, including sold-out showings at both Sundance and the True/False fests before its television premiere on May 4th. However, anticipation for the film's soundtrack is about to hit fever pitch as director Brett Morgen revealed that the accompanying album will feature "a mind-blowing 12-minute acoustic Cobain unheard track," the filmmaker tweeted (via Loudwire).

There are no other details regarding the song or if the track was intended for a solo album he worked on with Pat Smear and Eric Erlandson, other than it will feature on the Montage of Heck soundtrack. While an April 7th release date has been scheduled for the film's companion book, which features "a mixture of animation stills, rare photography and other treasures from Kurt Cobain's personal archive," no date or further information has been announced regarding the film's soundtrack.

All Nirvana parties appear to be involved from Cobain family members to former band mates as well. The doc "Kurt Cobain: Montage of Heck" will premiere on HBO on May 4th
