I have observed over the years that when institutions like the New York Philharmonic present a world premiere, the work is placed somewhere in the middle of a concert, for the good reason that when it is programmed last, the audience usually bolts for the door.
New “classical” music is not popular in the concert halls. It is, as a rule, incomprehensible and prompts a long, equally incomprehensible explanation in the program notes. One has come to suspect that the composer is not speaking from the heart, not telling the truth, but trying to create a sensation, to shock us, to impress us with his brilliance and originality. The old truism comes to mind that people say many stupid things when their sole motivation is to say something original.
