 The Piano Concerto in D-flat was written for Lev Oborin, who premiered it in Moscow on 12 July 1937, with the Moscow Philharmonic Orchestra under Lev Steinberg.The only piano available for the premiere was an upright piano, and the orchestra had just one rehearsal.The venue was an open-air stage in Sokolniki Park, and during the performance a strong wind blew Steinberg's glasses off, so that he could no longer see the score and had to conduct the remainder from memory.
