We don't live life as a scripted thing. Two boxers go into the ring and imporvise. You go make love with someone and you improvise. Go to sports car races, total improvisation. To 'know' is to be sterile.
Definition is death.
That's why I never buy records by bands I go to see live often. I regard my own recordings as tombstones or business cards. This is intriguing, and an obvious exception to my penchant for improvisation. Another thing that renders pop banal is remembering what comes next when you hear a song.
