The latest Kurt Cobain documentary, Montage of Heck, was directed by daughter Frances Bean and includes never-before-seen footage of the iconic rocker both in childhood and near his death. For grunge fans, it's the best news imaginable. For Foo Fighter founder and Nirvana drummer Dave Grohl, it sucks. Big time.

The rockstar was apparently "terrified" of the doc, as revealed in a new interview with the Washington Post.

The piece reads:

"Grohl was lying next to his wife in bed the other night when she came across the recent Cobain documentary, Montage of Heck. He was 'terrified,' he said, and figures he caught the one portion of the movie—a sliver in the middle—he could stand to watch. 'All the footage of him as a child, I think that might make me sad, and then the dark stuff at the end I think would bum me out,' Grohl said. So after 10 minutes, he rolled over and went to sleep. And anyway, he had to be up at 6 to take the kids to school."
