20 by Dmitri Shostakovich was first performed by the Leningrad Philharmonic Orchestra and Academy Capella Choir under Aleksandr Gauk on 21 January 1930 (the anniversary of Lenin's death).
Like the Second Symphony, the Third was written at a time when the freedom and modernism of the New Economic Policy (NEP) was giving way to the dominance of the Russian Association of Proletarian Musicians.
The Third more obviously reflects the latter's demands for clear, simple expression of musical and political ideas, in its largely diatonic writing, its insistent rhythms, its remaining largely fixed in the 'home' key of E-flat, its episodic nature, and in the use of a revolutionary text as a finale to deliver a clear, politically attuned message.
[1] In his report to the Leningrad Conservatory (1929), Shostakovich wrote “While in the [Second Symphony] the main content is struggle, the “May First” expresses the festive spirit of peaceful construction, if I may put it that way.
Boris Asafyev called it "the birth of the symphony out of the dynamism of revolutionary oratory",[3] and it was quickly performed in America by Leopold Stokowski, in Philadelphia in 1932 and at Carnegie Hall in early 1933.
[4] As Soviet musical ideas changed and central control developed with the concept of Socialist Realism in the 1930s the Third was branded a symbol of "formalism" and dropped from the repertoire.
