Frogman, calling this better than that, amplifies the subjectivity of this music. "Better" is a bad choice of words. Although the difference between Bill Evans, and Bobby Timmons is as wide as the Pacific Ocean, "better" is a word that could be left out of the discussion.
Bobby Timmons music projects a philosophical, and sociological point of view, that is probably foreign to Bill Evans, and vice versa. The fact that both of these individuals can strike a piano key, and say more than a short story is incredible; however, just as frequency is all important, whenever music is sent and received by transmitter and receiver; so it is by musician and audience; they both have to be on the same wavelenth.
No one has sent messages that have encompassed the depth and volume of Bobby Timmons music. People who can neither read nor write, understand Bobby Timmons musical messages. Bill Evans music is beautiful and eloquent, and comparing the two is apples and oranges.
Those eloquent discussions in that documentary were an attempt to come to some "objective" conclusion in the "subjective" world of music. They would have had to include the music of "Charles Mingus" in order to bring it closer to the truth. " Fables Of Faubus" is every bit as dynamite, as the tune "Kind Of Blue"

As a matter of fact, the inclusion of "Mingus Ah Um Charles Mingus" would have made the discussion more objective, and less like a "Miles Davis fan club"
Enjoy the music.
