Re: Joey Jordison
His speed, precision and technical ability are amazing, imo. The only Slipknot CD I have is The Subliminal Verses, so I'm basing my opinion mostly on that. As far as style goes, what he plays fits the band's sound. Sometimes he seems a little dry/mechanical, to me: fast, energetic and precise, but not much groove.
He is highly respectable as a drummer, at the very least. I can see why he has so many fans.
