Pierre Boulez once told me that Mozart was ‘trivial’ and he would never waste his time conducting such music. At the New York Philharmonic, he added, he persuaded them to substitute Haydn for Mozart. This was in 1985.
Now, a diligent Slipped Disc reader has come up with the facts, which are not quite as Pierre remembered them.
Boulez conducted these works by Mozart with the NY Phil (source: NY Phil digital archives), in all, 33 performances of Mozart:

Finally, who could forget this remarkable performance of Mozart’s Piano Concerto No. 20 with Maria Joao Pires and the Berlin Phil?
