It's an oft-told tale. A little girl, attending her first live symphony concert, is enthralled by the imposing conductor waving a baton. She turns to her parents: “Mommy, Daddy, that’s what I want to do when I grow up.” A little boy, hearing a flute or a clarinet or a violin or a tuba for the first time, is mesmerized. He clamors for an instrument of his own. Decades later, that little boy and girl have become internationally acclaimed musicians accepting the applause of audiences from San Francisco to Sydney, Australia.
