There are those who can point to one moment in their lives and say, "That was it. That was when everything changed forever." It's likely pianist Daniil Trifonov would point to June 30, 2011, as the day he knew things would never be the same. That was the day he won the International Tchaikovsky Competition, and went from being an unknown 20-year-old music student to being a star. Trifonov plays Tchaikovsky's First Piano Concerto in today's show.
