Dave Grohl is really building up expectations for the eighth Foo Fighters album.

Grohl tells the BBC that he wants to keep some mystery about what they're doing for the album. He explains, "I know what it sounds like, and I honestly think the entire concept is really going to take people by surprise and it sounds nuts. We recorded something the other day that's unlike anything we've ever done, and it starts with a fuse and then it explodes."

Grohl adds that he doesn't know when the album will be released.
