Definitely one for lovers of schadenfreude, this documentary shows the moment that pianist Maria Joao Pires realized that the concerto she had prepared was not the same one as the orchestra had just started playing.

Skip to 0’43 to catch her moment of realization, followed by a remarkably subtle argument between pianist and conductor Riccardo Chailly, which Maria loses.

Don’t worry – of course she knows the new concerto (Mozart’s No.20 in D minor, K.466), and of course she executes it magnificently. She’s a pro.
