Todd posted this on Facebook and I thought it was pretty interesting. I think that the basic premise of you play what you hear is so true that it's close to a "duh!", but putting it into practice can be difficult.
When I play, I often feel like I'm three different people simultaneously competing for dominance. There's a panicked animal that's just trying to keep his place and not screw up. There's this analytical guy saying, "OK, V7 coming up, diminished or altered scale?". And then there's this touchy-feely guy who's trying to guide the whole thing and make art.
