To me, Kurts time style seems very (intuit)ive. There is a whole system of second nature muscle memory combined with very unique micro subdivisions of rhythmic pattern.
also I can only imagine when you get to Kurts level of musical understanding that there are many 'trigger' points in different precussionists styles that manipulate how he interacts musically.
His playing obviously reflects piano as one of his primary instruments I believe. I think this contributes to the environment hes able to create rhythmicly and harmonicly.
Like many of you have described, his playing is modern...its wonderful to let my imagination try to subconciously compare some quotations of his phrasing to synthetic more contemporary approaches that we find in popular music today....but as this whole forum probably agrees, there isnt much of anything around that sounds like him.
