VERY interesting post ... it made me think and do some Googling. I came upon this article:
I especially like this: "The distance to the moment of creation has grown and what was at the outset the result of careful honing rather than the inspiration of the moment, comes to the listener, perfectly executed, but without a throbbing heart. The listener finds himself in a state of passive enjoyment, much like that of a visitor to a museum in front of a sculpture or painting."
Interesting stuff. Thanks for the thread Jeremy!
