Absolutely right, Bjorn. We have to be ourselves and let others be themselves in art. Preference also changes as we age too, sometimes quite markedly. The tendency to think there ought to exist some sort of universally constant artistic predilection over a lifetime, and that beauty at twenty is identical to beauty at sixty, is plainly wrong. Tomorrow I might suddenly find myself liking sounds I have avoided for sixty years, or vice-versa. It is not likely, but I am open to all serendipitous occurrences, it is part of the joy and fun of music. Even within a single improvisation I welcome surprise at every moment. To know everything that has happened, and will happen, seems to me a supremely pointless exercise, yet this is what musical orthodoxy asserts is right. It isn't right for me.
