Artistic expression

I participated in the 77th Ashiya Symphony Orchestra Regular Concert last night. Only the last program was a familiar melody to me.
Basically, I don't prefer dissonance of modern music with louder sound, I'm anxious about the health conditions all instruments that were obliged to work beyond their capacities, better study on the delicacy of the instruments, because biggest and loudest sound are not always meant the better artistic expression?
Also, all the instruments especially with some strings must be maintained after being abused?
Is it true by the way, that the conductor there last night had some intimate relations with Herbert von Karajan? The conductor should decide all of the artistic tastes of the playing music, no? He should tell unacceptable big and saturated noise from necessary fortissimo sound.

Today I would come to Kaizuka City near Kansai International Airport to meet with an old friend, who is enjoying Radio Control model airplane there, remembering past 25 years ago---.
