Here's another nice piece from Ted Warren at Trap'd- Warren's interview with saxophonist Jerry Bergonzi, who I did not know is also an accomplished drummer.
Go read the whole thing, but this is my favorite part:
Warren: You have studied your main instrument (Saxophone) very extensively and have written many books dealing with it, yet when you play you never sound calculated or cold. Did you consciously work on separating practice and performance?
Bergonzi: When I play I do not think of any of the things that I teach or have studied. I try to think the least amount possible and be in the moment. If I don't feel anything I don't hear anything. I have to feel something and when that happens a whole world of sound opens up. When the conscious mind comes in the creative mind leaves. 90% of the stuff that I ever practiced never got in my playing but it help develop some other things. It is a work in progress. There is no end and we are lucky for that. What else would we do. Make Money?
