Not even just shredding. I know 0 about guitar, so I might not be stating this correctly. I was poking around watching drumming videos of covers. I used to drum a little bit, so I still very much focus on that. Anyway, I was poking around and looking up lists of the hardest drum songs to play. Of course Tool and DT were up there with lots of talk about polyrhythms and lots of time signatures. I listen to a Tool song and even though it's complex, it still flows together. I listen to DT, and like I said, it just sounds like wankery and a bit "look at us". I don't throw the word around much, but pretentious does come to mind when I try to listen to DT. Talented as all get out though.
