Holy shit reviewing someone's playing on an album before the album comes out has got to be the dumbest thing that has gone on in these forums for years. I'm not talking about the The Tapes, I'm speaking of the general perception that people are getting about what Axe's drumming will be on the upcoming album. Lopez played in Amon Amarth before Opeth and his style wasn't even half as developed as it became after he'd been with Opeth for a few years. The style of band that Lopez previously played in called for that sort of drumming. Likewise, Axe's drumming in Bloodbath calls for a more straightforward style than Opeth calls for. There's no telling what his drumming will sound like when he's able to experiment and use different influences the way Mike allows his bandmates to do.
It MAY be a huge disappointment, but then again it MAY be a huge surprise. Let's just give him a chance and move on until then.
