Kit Armstrong is 12 years old, the youngest student at the prestigious Curtis Institute in Philadelphia. He’s also, according to his teachers, a musical genius of the kind that comes along once in a lifetime. “Have you heard about this kid named Kit Armstrong?” is the question of the moment in the small international community of impresarios who decide which artists land recitals in leading venues and perform with orchestras. His name is already circulating in the wider entertainment industry. He’s been on David Letterman, and handlers are busy fielding his many media requests.”
