I think that concrete poetry seems to have, as far as I can see, come to a kind of a dead end. It doesn't seem to be going any further than it went in its high period of about five or six years ago.
You're just sort of searching for this 'thing' and sometimes you get it and sometimes you don't. All music is imperfect, but in jazz since you're improvising, at least the way I play, I'm trying to follow my train of thought in a solo.
But in a tournament, you can be said in for all your money at any point so you can't make any mistakes so you have to, it's all about where you're sitting at the table.
