I prefer the bad performance of a superior pianist to the superior performance of a bad pianist.
It reminds me of Churchill's reply to the indignant remark that he was drunk at a reception:
"Hwell, milady, I'lllbees-sobertomorromorning, but youwill still-be-ugly."
A musician cannot be a skeptic because musical syntax speaks through the emotional force of expectation, and to anticipate and experience resolution he has to suspend disbelief.
Wanting and trying to play a piece that is too advanced to master is preposterous! It is the futile attempt to harvest before cultivation. Before the after: pre - posterous.
When will the star pianist promote our corporation and high art will serve to glorify our product?
A music critic should have musical, historical, and psychological education. He should also passionately love music and have utmost respect for the performer in general. A classical concert artist spent a lifetime to arrive at mastery at an instrument and the authority of an individual interpretation ~ the responsibility of a music critic is an attempt of an educated understanding and emphatic explanation rather than the self-indulgent expression of stereotypes based on established and/or personal taste alone. A music critic should also be able to write good.

"Good show". What an awful and completely inappropriate expression for the offering and sharing of an artist.
"Good job". How terrible and underwhelming. When a plumber installs a toilet and it's not leaking, that is a 'good job'.
"Well done" is not much better; but it's an appropriate expression for the preparation of steak.
What should one say?
Small minds express banality through mannerisms.
Average minds express triviality through technique.
Great minds express truth and beauty through mastery.
One should – with exceptions – perform in concert only the most outstanding pieces of the great composers written specifically for that purpose ~ because the domain of art is immeasurable, life is short, opportunity is transient, exploration is treacherous, fair assessment is unfathomable, and pieces not written for public performance are, well, not written for public performance. One should however – without exception and for the same reasons – comprehensively study musical and instrumental art as well as the complete repertoire of the great composers.
