What appears to be missing in that piece is the notion that some people actually are better, deeper musicians than others. It is truly hard for some players to come to grips with the fact that there are people who play on a level which most of us are capable of appreciating but not of achieving. (I don't know Mr. Anschell; this is not meant as a comment on him or his musicianship.)
A number of points flow from and relate to that truth. Among them, in no particular order:
a) People Who Do Not Play As Well As Michael Brecker ("us" or "we" for short) nevertheless have something musical to offer the world.
b) Musically, what we have to offer is almost certain to not be playing concerts for rapt, clued-in audiences. Those situations tend to go to People Who Do Play As Well As Michael Brecker because they produce rapture-inducing noises lots more frequently than we do.
c) Playing for us often mixes joy and frustration. We love to make that noise we love but we know that we are not reaching the musical level of the record we were listening to in the car on the way to the gig.
d) Even though we feel frustrated not to reach our desired level, many people who hear us derive FULL satisfaction from the experience. Our choice is either to look down on those people because they are too ignorant to appreciate our suckiness or to embrace the opportunity to provide them with the moment they seek. As far as I can tell there are no other choices. Every gig I play is a gig I CHOOSE to play. The responsibility for my spending time in an unsatisfactory musical situation is mine alone.
e) If there are musical education programs which tend to prepare us for any of this, I didn't find them.
I like my work, wife, kids, and I like my music. I came to grips years ago with the facts that 1) I am insufficiently obsessive/compulsive to focus on music to the extent required to fully realize my skills and 2) if it were otherwise I still did not have it in me to Play As Well As Michael Brecker. All I can do it struggle to grow and enjoy on my modest level, and dig my wife, kids and work.
There's lots more to say but I have to work.
