Branson is a very bad place for those of us who love dulcimers. I took got hooked on dulcimers in Branson (specifically Silver Dollar City) many years ago. During my last visit to Branson in June I bought a new Cedar Creek dulcimer which I just love. More info and pictures at: http://members.tripod.com/lddulcimer/dulcimers.htm
I am not sure who the dulcimer player is that you heard. One of the sad things I noticed the last two times I was at Silver Dollar City was the lack of musicians playing on the grounds. There used to be at least a few dulcimer players playing each time I went there. But, this season is our first back in over 10 years and it seems that there are very few musicians anymore.
I am looking forward to the Silver Dollar City music fest in the Fall.
