There have been a handful of Kurt Cobain documentaries since the Nirvana frontman died in 1994, but fans won’t want to miss the latest from filmmaker Brett Morgen – “Kurt Cobain: Montage of Heck.” A trailer for the HBO film was released Wednesday, giving Nirvana lovers their first taste of what is being hailed as the must-see documentary of the year.

The flick premiered at the Sundance Film Festival on Jan. 24, and is scheduled to air again at SXSW Film Festival on Wednesday, March 18. What sets “Montage of Heck” apart from the others is that it features never-before-seen home videos, photos and new interviews with his family. Cobain’s only child, Frances Bean, is also attached to the project as an executive producer.

As previously reported, the documentary will focus on Cobain’s life, rather than his 1994 suicide. The trailer gives viewers a look at just that, highlighting Cobain as an artist, his success with Nirvana and his family life with wife Courtney Love and daughter Frances Bean. Footage featuring Cobain with them gives a rare look into the grunge rocker’s role as a husband and father.

“Kurt Cobain: Montage of Heck” will premiere on HBO on May 4. Watch the trailer below:
