Foo Fighters: Sonic Highways debuts on HBO in October and the as-yet-untitled album will be released in November.

He added, that while working on Sound City he learned that fusing music and documentary together could reach a whole new audience. “Music can seem a little one dimensional…but when you get a little deeper into the artist or the song, it creates this emotional connection,” he said.

Grohl took a good-natured swipe at TV’s many music competition shows. Making music, he said, should not be about standing in a lineup to “have a bazillionaire tell you that you are a bad singer. Don’t get me started …” he joked.
