“When you improvise, and you play something for the first time, you kind of play it at its peak. And if you kind of like play something and then you think ‘oh I like that’ and then you replay it, you never quite get it. It’s like the thing of demoing, y’know if you demo a track, no matter how badly you try to demo it, there will always be a quality within it that you subsequently would try to recreate, which you shouldn’t do.”
