Rok, I have read through this whole last week's posts on this thread and I still have no idea a) just exactly what you think you mean by "nuts and bolts" and b) why you apparently set no value on it. Frogman made a valiant attempt to explain, and I'm not sure I can add to his.
The thing that puzzles me the most is when you say you don't buy it that artists have great appreciation for others in their field who do things very differently from them. Frankly, your position and arguments make no sense. Why wouldn't Renee Fleming appreciate Ella Fitzgerald? Why wouldn't Wynton appreciate Miles? Why wouldn't Picasso appreciate Matisse? Why wouldn't Shakespeare appreciate Joyce? Or the other way around in any of these examples?? Great artists will always respect the craft of others (is this term more acceptable to you?), even if they dislike what is being created with that craft. You can substitute the violin examples earlier instead, but as a brass player it is more natural for me to bring up the trumpet ones - absolutely no one, even the people who hate him, would ever say that Wynton could not play, or disrespect his craft. He has this in spades, more than any other jazz trumpeter ever, and all the others greatly appreciate it, even if they don't care for the music he makes with it. Everyone who is any good at all has worked very hard at their craft, and appreciates others who have done the same. Same thing in the world of athletics. When two of the best are battling it out, whether it be individual or team sports, the opponents have to have the utmost respect for each other's game, even if they are very different styles, and they don't like each other's style, or don't like them personally, or whatever.
