Well, its a concept album, you're allowed to play it in its entirety live.
Rob sounds like he's starting to take things a bit too seriously though. I'm beginning to think bands shouldn't talk about their new albums. All it does it hype people up, which makes less room for enjoyment and more room for being dissapointed.
I listened to three Babymetal tracks...sounds like Chun Li getting butt-fucked by Andrew W.K. That's not something I ever wanted to hear.
