Union of Soviet Composers
The musical patriarchs of the era were Prokofiev, Shostakovich, Aram Khachaturian and Alexander Alexandrov. The latter is best known for composing the Anthem of the Soviet Union and the song "The Sacred War". With time, a wave of younger Soviet composers, such as Georgy Sviridov, Alfred Schnittke, and Sofia Gubaidulina took the forefront due to the rigorous Soviet education system. The Union of Soviet Composers was established in 1932 and became the major regulatory body for Soviet music.
