I always had my suspicions about that whole teaching old dogs new tricks proposition. i mean, sure, you quite possibly could teach Yo-Yo Ma to play the valve trombone, but why would you want to? He seems to be doing quite well with what he's doing now -- let him stay focused on that. Sometimes it's better to let the old dogs do their old tricks again and again until they have got 'em down perfectly, thus the trick becomes making sure there is no separation, no difference between the dog and the trick. That's how workmen become craftsmen, and how craftsmen become master craftsmen, and how master craftsmen become artists.
If your ever in the mood for some sweet ass blues piano, here's an old dog who knew a trick or two and he played 'em with relish and style.
(There are moments during his performance of "Apex Blues" when Mr. Hodes rather loudly and exuberantly kept time with his foot on the studio floor. Listening to this disc on the player in my car. whenever his foot hit the floor, I could actually feel the floor of my car vibrate. As Dame Edna would say, "Spoooooooooky".)
You're quite right!
