I don't play the traditional Charlie Parker songs. But I do improvise and I do create with my instrument, and that to me is jazz. But there are people who use the word 'jazz' only in a traditional sense, and they would be offended by that, and that's fine.
It took a long time, but I have learned that you just can't take anything you want out of life without putting something back in exchange.
What I have crossed out I didn't like. What I haven't crossed out I'm dissatisfied with.
