When we were supposed to visit St. Petersburg, my wife was very anxious to see a ballet (not the one in FL). I was going to oblige, it was quite pricey. I could tolerate 3 hours of something I don't really understand usually. The opera was pretty rough on me though, I got up and walked about the building a few times. Die Zauberflote.
There are parts with well known music and vast tracts with ... boring stuff.
Anyway, I was spared the ballet, and having never been to one I admit to be very slightly curious, but we've all seen segments on TV. After a minute or so, I don't get it.
I have noted that symphonies often play, um, weird compositions, often something modern, with the composer present. I have heard one that was "OK", the rest are discordant nonsense, to me, that sound like the symphony when they are tuning.
I'd prefer they stuck with the classics, which are classics for good reason.
