I have a feeling this isn't a health thing. Just the way Mikael spoke about it in leeds, he didn't say he was unwell, he said he wasn't fit to play with Opeth, which could mean anything. Then he made us all Shout MARTIN'S A FUCKING CUNT (because axe is called martin too... but it seemed a bit codeish to me). Maybe I'm just paranoid.
Either way, I have to agree that the people who are bashing Axe are being pretty ungrateful. He was doing a damn good job from what I saw. He was actually playing Lopez's beats and arrangements, not his own, and he didn't screw anything up. Thats a feat. Maybe just didn't play with the same comfort and confidence Lopez would have... But I'm so glad Axe was there to fill the spot.
And Ghost Of Perdition sounded fucking awesome slow. And it wasn't even significantly slowed down, I think it's just the sound Opeth are sporting right now, really heavy toms and snare and subtle cymbals with the bass and distorted guitars hitting really really low ends.
