Choices, it's about making choices. You like modern classical, drive on. It's not for me, at least not most of it. On my father, about the closest he got to modern was maybe Erin Copeland. His orchestra did do a few pieces from Copeland that were very nice. Not sure how old you are, but the Boston Classical Orchestra performed at Faneuil Hall. Here's a Mozart Sonata. Mozart was his favorite for sure:
Surely you've read enough ASR to know that Mozart is twiddly-dink music not worth the time of real manly men.
I'm not from the Boston area, so I'm not familiar with the local orchestras unless they recorded extensively.
Professional musicians who spend decades learning their craft are understandably often very focused on a particular repertoire because rehearsal time for unknown music is limited and expensive, renting new orchestral parts is also expensive, and they must consider what will sell concert tickets to the audience they have spent years building. They have much more to lose than just an hour spent listening to a disappointing recording.
I try not to be dismissive of music I have not heard or given a fair shake, though I did that plenty when I was young and knew everything. I still struggle to overcome old prejudices about music. In particular, I find the cynicism and narrow-mindedness of so many here on ASR about music they've never really made a good-faith effort to engage with to be poisonous. To continue with the analogy, we have to let the horses run, the race has to be fair, and we need to see a fair number of races before our opinion of the horses might be considered interesting.
