Pryso asks an interesting question. I agree with all that Rok wrote, but I think that there is, in fact, an answer to the question……in my book, anyway.
OP was an amazing piano player and, to my ears, he definitely had a style. He was a master of just about every Jazz piano style and I think that his personal style can be said to have been heavily informed by all those styles; not the least of which was his early training in Classical piano. Still, I think the most prominent influence in his playing was that of Art Tatum. I agree with Pryso, he never really sounded like a bebop player to me. If I were to get analytical, I would say that, harmonically, he was more of a traditionalist and, in the same spirit, he played more on the front side of the beat than most bebop and certainly hard bop players.
