You never can overwhelm an instrument. You will never get out all that's in an instrument. An instrument will bring you to your limits.
Many times during auditions, I was told that I couldn't carry a note with a bucket, and that I sure couldn't play the piano.
Music is about the only thing left that people don't fight over.
The important thing is to feel your music, really feel it and believe it.
Don't go backwards - you've already been there.
I don't sing a song unless I feel it. The song don't tug at my heart, I pass on it. I have to believe in what I'm doing.
