HBO will air the authorized Kurt Cobain documentary Kurt Cobain: Montage of Heck, executive produced by Cobain’s daughter Frances Bean, on May 4. It’s also hitting theaters around the world beginning April 10.

Today, a new excerpt from the film has been released, via The Guardian. In it, pages from Cobain’s diaries are animated to show the litany of rejected band names Cobain came up with before settling on Nirvana.
