I attended Galax only once, alas, some years ago; it was wonderful. I was expecting wonderful instrumentalists (the name assures that) but was fascinated by the quality of the singing.
They used to make cassettes of some of the best, from each year; might check and see if there are annual CDs coming out.
It was very easy to find my way around and find what was happening where and when, as well.
It is in a beautiful area, too.
I would go back in a heartbeat.
