Kurt CobainITS been revealed that 2015 will see the release of a new and revealing Kurt Cobain documentary featuring the Seattle troubled genius of Nirvana.

Having initially premiered at this year’s Sundance Festival to a great deal of fervour and critical acclaim, the film integrates both animation and never before seen home video footage to provide an all encompassing portrait of the the greatest artist’s of the 90s.

Featuring contributions from a string of his cohorts  and family members including Nirvana bassist Krist Novoselic and his widow Courtney Love, Director Brett Morgan has revealed that the film’s score will consist entirely of unreleased music from the late musician.

The documentary is set to be screened at this month’s South By Southwest Conference, before a theatrical release in the UK this spring.
