Although I never saw him play either, my guess would be 10 percent of the sound was the studio (mike technique, processing, etc), another 10 percent could be the drums he played (tuning, sticks, heads, build of the set, etc), and the remaining 90 percent was the man himself, and his ability to control his playing, and translate his emotion to what he played, so on and so forth.
(I guess that about makes the 110 worth of percent performance I generally heard from him)
