Violinist Nicola Benedetti defies conventional wisdom. When she was a finalist at the BBC Young Artist Competition, she didn't play an impressive, well-known warhorse. She chose the obscure and wildly atmospheric Violin Concerto No. 1 by Karol Szymanowski. She won. That led to a 1.7 million dollar major-label recording contract, and now at age 22, she's still playing that Szymanowski concerto.
