It happens all the time.
I hear it on the bandstand at every gig I play. Rock, pop, country, even jazz. Sometimes I hear it from guys that have won Grammys. I hear it from me. Musicians stop thinking and listening and the life just leaves the music.
They're playing the right notes, mind you, but they switch on the "autopilot" and the spirit leaves and the bottom drops out of the energy, thus "aping the outer shell of an idea."
This makes it Very difficult to endure. As a free-lancer, I get the calls because I can carry people who do this, who believe that nobody can tell if they're distracted, thinking of what they have to do tomorrow...
But they DO know that with lesser sidemen surrounding them s**t falls apart. "Hmmm... why do things seem to groove so much better when Clark is on the gig?"
"Why does the singer sound so much more in tune? Could it be because I've hired Clark? Nah. A piano player really can't affect these things."
Yes I can.
It happens all the time.
A great majority of musicians who listen to this live music don't hear these subtleties. But they DO know when things are really clicking.
Think about it:
Some of the greatest studio musicians get famous for playing ridiculously simple rhythm parts on a Steely Dan recording, let's say. Why is that? What is so mysterious about playing quarter notes on a hihat?
"I'd do that too if I could get triple scale!" an ignorant musician would say.
