 Among the other luminaries who played with the Philharmonic were pianists Ignacy Jan Paderewski and Arthur Rubinstein, violinists Jascha Heifetz and Pablo de Sarasate, and cellist Pablo Casals.
 The Philharmonic has played host to the Chopin International Piano Competition since the contest began in 1927, and also appeared at the inaugural Wieniawski International Violin Competition (1935) and Universal Festival of Polish Art (1937).
