Dear Rok2id, you're probably a good person and a gentleman also, but hardly in the mainstream of jazz critics. D.Brubeck made a significant contribution to the musical arts and was a master of polyrhythms, who could play one with the left hand and another with the right (not easy, you try it and see). His group with Paul Desmond on sax sounded amazing even if you knew nothing about jazz or imporvisation, and revealed even more to fans who were more deeply involved in the music. I wouldn't try to rank him amongst all the great pianists and composers anymore than i would try to say who was better, Basie or Ellington.
He was a great musician and i would suggest a certain album that i am crazy about and was until recently out of print- called My Favorite Things. I have the Japanese import CD and the vinyl as well. this is one beautiful note after another. i for one will really miss the guys who made this music possible.
