Dave Grohl has been busy working with other artists including Ghost (Ghost B.C.) and country superstars the Zac Brown Band. Now he's turning his attention back to Foo Fighters, and has just made an interesting statement about their next album.

In an interview with Rolling Stone at the American Music Awards, Grohl talked about the Foos' next album. "It’s badass," he exclaimed. "We’re doing something that nobody knows about, it’s f--king rad. We begin recording soon, but we’re doing it in a way that no one’s done before and we’re writing the album in a way that I don’t think has been done before."

Grohl didn't elaborate on that statement, so we'll have to wait for more details on exactly what he means by writing and recording an album in way that hasn't been done before. The record will be the follow-up to 2011's 'Wasting Light.'

Foo Fighters haven't played live in a while, but that hiatus will end next month. They are set to play shows in Mexico City on Dec. 11 and 13.
