Collen tells WAAF: "I think it's the best thing we've done since Hysteria - I really do. It's the loudest rock guitars we've ever had." And he believes the project is all the stronger for having developed organically. "We thought we were going to do an EP or a single, and we came out with 12 songs, and now we've got 14," he says.

"There wasn't any industry - no record company executive or anyone saying, 'You've got to do an album.' It was purely because we wanted to write songs, and we felt the need to do that.
