Morgan Rose - Sevendust! If you ever get the chance to see them live, you will know why I said him. The man can trow sticks, knok over a cymbal stand and pull it back up with his feet and sing back-up and play the most kick ass drum parts and never miss a lick!
Mike Portnoy's not a bad drummer at all, don't get me wrong. He's got the rythm, great technique, and good precision. But... musicality? He's more of a loud, aggresive drummer than a musician. But then again maybe its the music style of Dream Theatre. If you've ever heard of Liquid Tenson Experiment, you've recognized how diverse the songs are. He plays more expressively in some styles than other. Im just fed up with Mike Portnoy being classified as the end all be all Best Drummer ever.
