Shostakovich's Eighth Quartet from 1960 is autobiographical in nature, referencing personal struggles and experiences through self-quotations and allusions. Specifically, it quotes from his First and Fifth Symphonies, as well as a Russian revolutionary song about prison hardship. The work is a highly personal reflection on Shostakovich's life under Soviet rule, his joining of the Communist Party, and his inner anguish, loneliness, and thoughts of suicide during a difficult period. It stands as one of the most profound and successful string quartets of the 20th century.
