Ok, I want to try and say this without sounding negitive. I personally don't hear the subbtle nuances in Axe's druming that I did with Lopez's. However, I can see how these traits might develop over time, as Axe becomes more and more comfortable with Opeth. Also consider these two guys have completely different backgrounds in drumming, and while we have developed a taste for Lopez's latin roots, some good old asskicking blast beats is a welcome change.
I can say nothing bad about what I've heard from watershed, it's very technical and very tight.
I hear a lot of small details in Axe's drumming. Not like Lopez, sure (at least not like Lopez on GR), but damn he does an amazing job at keeping it interesting and leaving a lot below the surface. He has zero soft parts on either of these songs, too, so I'm looking forward to what he does there.
