Polish pianist Krystian Zimerman surprised the audience at his recital in the Italian city of Macerata earlier this week. Instead of performing on his own Steinway, as he uses to do, he played on an old instrument he had discovered backstage at the Teatro Lauro Rossi, the recital venue. Together with the piano tuner Antonino Rappoccio, he took the piano apart, piece by piece, and later put everything together, with the necessary regulations made, and went to play his much applauded recital on the old grand, also a Steinway, as the Italian press reports.
