The Concerto in C minor for Piano, Trumpet, and String Orchestra, Op. 35, was completed by Dmitri Shostakovich in 1933 and premiered on 15 October, 1933 by the Leningrad Philharmonic Orchestra with Shostakovich at the piano, Fritz Stiedry conducting, and Alexander Schmidt playing the trumpet solos. Shostakovich recalled that he had initially planned to write a concerto for trumpet and orchestra but then added the piano to make it a double concerto; indeed, both instruments have equally prominent roles.
