10/25/17. I watched this out of curiosity because I have heard of them over the years. I didn't realize that David Grohl was the drummer for Nirvana. But, he successfully transitioned to front man for the Foo Fighters. The music is all right, but I am just not used to Grohl screaming into the mike most of the time. That's passion for you! A decent music documentary that offers backstage inside talk and a generous helping of concert footage. Foo Fighters fans will probably love this one.
