mountain music from white top mountain in SE Va.

Re-locating to Ft Collins in June. Very interested in Rocky Grass in Lyons. Wondering how performers are chosen for Rocky Grass???? I would love for people to hear some ole time mountain music straight from White Top Mountain in SE Virginia. there is a great group from that area called the White Top Mountain Band. It's a family band with heavy emphasis on banjo and fiddle. Folks in this area do a lot of "flat-footin" at all their performances. Probably a lot different from the usual groups at RG. Might be different style but fast moving and a lot of fun! Any chance they could be invited????? Anyone have any idea about this type of music??? Give me some feedback. Thanks
