Cantata for the 20th Anniversary of the October Revolution (Prokofiev)
Upon the première of "Songs of Our Days" in 1938, Prokofiev hoped that the success of the piece would "soften hard hearts". Sadly, the Cantata never received official approval during Prokofiev's lifetime. The cantata was forgotten until 1966, when it finally premiered, being conducted by Kirill Kondrashin. However, the piece suffered from censorship. Stalin had died in 1953, and had been publicly denounced. Through the de-stalinization of the piece, the two movements "The Pledge" and "Constitution" were completely removed. Still a third movement, the 9th, "Symphony", was heavily modified. Having removed the finale of the piece, Kondrashin finished the piece by reprising the second movement; "The Philosophers".
