We knew the new documentary on Kurt Cobain got rave reviews, now we can judge for ourselves as the trailer has been released...and it looks brilliant.
Cobain: Montage of Heck focuses on Kurt from birth all the way through to his Nirvana days and his untimely death at the age of 27 in 1994.
It premiered at the Sundance Film Festival and it's due in selected cinemas before it shows on US television on HBO on May 4th.
Kurt's daughter with Courtney Love - Frances Bean Cobain - is executive producer and it contains lots of family home videos as well as interviews with his father, mother and sister and animated recreations of Kurt's life.
In fact, 85% of the material in 'Montage of Heck' has never been seen or rarely seen.
It's directed by Brett Morgen, who we told you before, tweeted the soundtrack will have a previously unheard 12-minute acoustic track.
Watch the trailer below...
Kurt Cobain will be 21 years dead on April 5th next.
