Foo Fighters frontman Dave Grohl has said that the concept of their upcoming eight studio album will take fans by surprise.
Speaking to Zane Lowe on BBC Radio 1 Grohl said, "We haven't really disclosed exactly what we are doing. We're doing something that no-one really knows about and we'll announce pretty soon I think.
"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."
