In a recent concert in Vienna, pianist Yefim Bronfman was set to perform a Bartok piano concerto. There was a bit of a problem, what could be a significant problem for a pianist... he'd just gotten a bad cut on his finger. A polished professional, Bronfman insisted on going through with the performance, despite the pain and continued bleeding. On Thursday's Performance Today, we'll hear Bronfman give a less sticky performance of Bela Bartok's Piano Concerto No. 3, with the London Symphony Orchestra and conductor Valery Gergiev.
