I think people should be realistic with what they're expecting from MM on this upcoming album. I think his playing on TEI is very representative of his style. We could possibly get a little more crazy technique and intricate and musically interesting parts on the next album in terms of drumming, but I don't think it's going to be that much different from this combined with ADToE.
In my opinion, this expectation has its roots in the drum auditions. People forget how many people wanted other drummers for precisely this reason-- that MM's parts would be less musically "interesting" than say Marco's. MM is a classically trained rock and heavy music drummer, with fluency in many of their subgenres. His playing on TEI is indicative of that overall style. I think we will get a little more, but I don't expect him to take over the album with his playing. That is not why DT picked him. The guys who TRIED to do too much of what I'm sayng MM won't do, didn't get the gig. If DT were going with guys who could play the most technical intricate and interesting drum parts in DT songs, they should have gone with Virgil. But they did not.
TEI is a great piece of drumming on many levels. I also hope to see a bit more, but I'm not going to be heartbroken or shocked if we only get a smidge extra. We shall see.
