You mentioned Monk. Try to imagine his career without the dedication of Alfred Lion and Francis Wolff, Bob Weinstock, and Orrin Keepnews. Given his personal difficulties, I think it unlikely that we would ever have heard his music without their support. I love Thelonious. I have everything he ever recorded (I hope) in my collection of LPs and CDs. I do not think that his success can be attributed to the appreciation by African Americans alone.
I think we’re talking past each other a bit. As Dylan once sang (mixing metaphors wildly here) we always did feel the same we just saw it from a different point of view. I’m likely guilty of a too literal reading of your original comment.
