Few players of any age show the level of comfort onstage that 14-year-old Sarah Chang displays with her fiddle, as the teenager proved again Friday night during a performance with the Philadelphia Orchestra.
The Henri Vieuxtemps Violin Concerto No. 5 in A minor was the first orchestra solo Chang performed at the Mann Music Center, attending to its spirals of melody with an ease that belies its difficulties.
It is a funny kettle of fish, this Vieuxtemps - music whose flowing elegance seems not merely a century removed from us, but even a galaxy. If a veteran listener finds it difficult to discern what this music is saying - cocktail chitchat or soulful sustenance? - whatever can the mind of an adolescent make of it?
