I love the idea of a song being this living, breathing sort of thing. It can exist in a state of flux, always taking on a slightly different form and varying from night to night. You have a recording, and that’s great…. but that’s just the song in the form it occurred the day or week it happened to be recorded. Its so much stronger (to me) when it can exist beyond that, and change form and evolve naturally. I guess that’s why I hate the idea of backing tracks live…. you’ve killed your song at that point. It can’t grow any more, so that you aren’t playing a show, you’re playing a funeral. How boring, to play a funeral night after night.
