Foo Fighters’ Sonic Highways documentary was a huge hit, and now Dave Grohl tells Rolling Stone that he has the “concept” for a season two already and that it will made “someday”.

“Well, we’ve been working on it for six years now, and . . . I’m kidding. That door is always open. And a lot of great things have stemmed from that series. There are now kids in schools across the country making their own Sonic Highways about the little towns where they live. I still have the concept for the second season, so, someday.”
