Alfred Schnittke (1934-1998) was a Russian composer and one of the most significant composers of the 20th century. His music style was a blend of various influences including Russian, German, and Polish traditions, creating a unique and experimental sound that challenged conventional forms. Schnittke's works often incorporated elements of polystylism, where he would juxtapose and fuse together different musical styles and historical periods in a single composition. Despite facing political and artistic restrictions under the Soviet regime, Schnittke gained international recognition for his compositions that explored themes of spirituality, suffering, and human existence.
