Im a drummer...not pro, just a crazy amature. Phil, for those who understand drumming technique, is an AMAZING drummer. Period. The only reason that he has Chester playing with him (aside from the fact that hes an excellent drummer) is because Phil cannot sing and drum to every song. Its quite simple. He is one of the most relaxed technical drummers out there. So much so, that he looks like he is not doing much. Thats one way you can tell whos great and who ok. Vinnie Coliuta (studio drummer and most recently with Sting) is VERY technical and it shows. But that does not necessarily means he is better than Phil (as an example). If you want to see, or hear, one of the BEST drummers of all time (IMHO) check out Billy Cobham.
