if you mean 'tasteful', mass-apprecitated music, I fear that it will be fleet foxes or wilco, or more likely radiohead unfortunately. but if you mean bands that make at least one solid album every year for ten years, that's wide open. We've got plenty of prolificacy, but real, sustained quality? Hmmm. I would like it to be home blitz or so cow. Wait, I have already put too much time into this question. This is dumb.
