Through the years we’ve seen journalists try (and fail,) to get authorization on a Kurt Cobain documentary. Brett Morgan was granted the kind of access other reporters could only dream of.

Montage of Heck was made with full cooperation from Cobain’s family including Courtney Love and their daughter Frances Bean. They also serve as executive producers for the project. The doc will include never before seen home videos, personal artwork, interviews, and much more from the Nirvana frontman. HBO will be airing it on May 4.
