Mozart is known to have performed his Piano Concerto No. 25 three times: its premiere in Vienna in late 1786, then twice more in early 1787 in Vienna then Leipzig. But after Mozart’s death in 1791, the Concerto fell into unwarranted neglect. It wasn’t until 147 years after Mozart's own final Vienna performance that it was performed again in that city in 1934. And not until World War II was the Concerto recognized as one of the great masterworks of the form and became part of the standard Concerto repertoire. A recording of the concerto performed on a fortepiano of Mozart’s time, with soloist Malcolm Bilson who celebrates his 90th birthday today, is today’s Midday Masterpiece.
