There are amazing players who are self taught, and there are awful ones. There are amazing players who are classically trained and there are awful ones. This is NOT the way to judge a musician! But before hearing a player, if you hear the words "self taught," in that instinctual gut-check part of yourself, do your expectations go up or down. Definitely explain your choice if you want, but lets avoid the lists of names if at all possible. I doubt there is a player alive who would say "all self taught players are good/bad" or "all trained players are good/bad." The examples either way sort of prove jack, and I'm wondering what your gut tells you.
