Not being knowledgeable about music, I can`t really say about Vassar with understanding. Everyone said he was so great, and though I enjoyed his playing, not all so much, over the top of my head I think. Restraint is a wonderful quality for artists I think, but it seems a difficult quality for laymen to fully appreciate. He seemed to be a different cut from most fiddlers I have seen. Other musicians show restraint that I really can appreciate from a listening to sense. JJ Cale was one, Clapton sometimes. There must be bluegrass players in that vein, perhaps yourself. Probably a sign of maturity.
