Well, I can't say that Mike Portnoy shaped the way I play drums, due to the fact that I don't listen to them. However, I'm not gonna bash him, because he's better than I am. Neal Peart however is an awesome drummer. They don't call him "The Professor" for nothing. I like to watch drummers with crazy, elaborate and complicated drum fills, but for the most part, I like pretty simple semi-complicated stuff, like Nick Mason. He's not the most technical drummer out there, but I could listen to him play drums all day long. A few drummers I like are Chad Smith, Nick Mason, Neal Peart, and Pete McCarthy to name a few. Now, there's many more out there that I like, but...
