Союз композиторов СССР
The music patriarchs of the era were Prokofiev, Shostakovich and Aram Khachaturian. 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.
