Watch The Gut-Wrenching Trailer For Kurt Cobain Doco 'Montage Of Heck'

The trailer for Brett Morgen's documentary about the life of Nirvana frontman Kurt Cobain, Montage Of Heck, has appeared online, and the response around the web has almost uniformly been defined by a sense of overwhelming sadness after viewing it.

With former partner Courtney Love and daughter Frances Bean Cobain steering the flick from behind the scenes as executive producers, Morgen was basically given carte blanche over Cobain's voluminous personal archives. In putting the film together, he uncovered an eye-popping amount of art, cassettes, writing, and even an audio autobiography from the 1980s, all of which conspire to paint arguably the most complete, and devastating, picture to date of the archetypal tortured genius that was Kurt Cobain.

Featuring interviews with friends, family and bandmates, as well as portions narrated by the late frontman himself (that autobiography would have come in handy), even the trailer is affecting, and goes a long way towards explaining why the film, following its inaugural unveiling at Sundance Film Festival, has been all but universally acclaimed by those who have seen it.

Watch the trailer below.

Montage Of Heck makes its US premier on HBO on 4 May, as well as a limited theatre run. There are no international airing details available, but we'll let you know if that changes any time soon.
