Ouch! Can you imagine showing up for rehearsal only to realize at the last minute that you've prepared the wrong concerto! That's what happened with Maria Joao Pires. At about the 43 seconds into the video clip, the look on her face tells the story -- and, more, what's truly remarkable is that after some encouragement from Maestro Chailly she is able to soldier on and pull call up from memory the correct concerto. Brava!
