The problem with the "mellow at first but gets heavy" tracks is Baroness are already spending way too much time being mellow to begin with. If you're rocking 6 tracks in a row, then you're allowed to switch it up like that. But the problem is, they're spending so much goddamn time being "beautiful" that by the time one of the "epic" tracks comes up, I'm too pissed off to care.
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.
