Charles Barr, 31, was the ultimate orchestral success story: he graduated from Curtis in 1997, became principal bassist of the Charleston Symphony shortly thereafter, and in 2002, landed a dream job in the bass section of the Cleveland Orchestra. He was an active outdoorsman and avid mountain biker. And all of that came to an abrupt and tragic end last week when Barr lost control of his bike and swerved into the path of a pickup truck.
