I think some of the other commenters pointing out that it reads as a command is probably a big one, but you did a pretty good job of explaining it here (imo). Even just saying to him that you want a heads up of if it’s good or bad and working out a system so you don’t stress would probably be a marked improvement for you, and I would bet it’d be an easy fix.
As someone who plays in an orchestra professionally, I totally 1000% agree with you. It’s a weird fine line that I enjoy music, but I do it as a career because I really enjoy playing with other people and the music itself is almost secondary. Good luck explaining that to people who Really Like Classical Music, lol.
There’s a lot of elitism in it and it sadly alienates a lot of would-be concert goers, I feel like.
