How have you handled the developing musician who really wants to play in a setting they simply aren't ready for? Maybe it's the chops they don't have, they can go practice for a few months and see where we are. Maybe it's just on-stage experience they don't have--that can be gained in smaller venues. Maybe they really are hopelessly unaware of how bad they are, and you don't think they will ever get good enough. But you can tell they are someone who probably won't take it well when you try and tell them no. How have you handled this well? Not so well? How about the difference between a singer and a musician? I mean, sometimes the musician can go get better, but a singer could spend the next decade practicing and still sound horrible. How can developing musicians show they are eager to learn and develop, but at the proper pace and in the proper venues?
