The most simple way to test your music is to look out and gauge the crowd. Or ask the question, “Is there a crowd?”
Noise is selfish. It writes its tunes in the key of “what’s in it for me.”
A true musician gets his fix on the response of his followers…i.e. what’s in it for them?
Did it move them? Did it take them somewhere? Did they experience something?
How are your ticket sales?
That’s a serious question with a serious answer.
Don’t blame your booking agent with your answer. He didn’t write your music.
