H for Hiring

Often when a concert pianist steps onto the stage to perform, they have to play a piano that has been hired. Surprisingly, while many are in great shape, sometimes they aren't. Sometimes they are appropriate for the repertoire about to be played and sometimes not. The challenge for the artist is to work out how to play this piano in such a way that the concert is the best it can be. How does a pianist coax a beautiful performance out of the hired concert grand? Featuring Pierre Laurent Aimard, Richard Sisson, Jonathan Biss and Ulrich Gerhartz.
