Edison Vasilievich Denisov (Russian: Эдисо́н Васи́льевич Дени́сов, 6 April 1929 – 24 November 1996) was a Russian composer in the so-called "Underground", "alternative" or "nonconformist" division of Soviet music.The house in Tomsk where Denisov was born; the memorial plaque is visible.Denisov was born in Tomsk, Siberia. He studied mathematics before deciding to spend his life composing. This decision was enthusiastically supported by Dmitri Shostakovich, who gave him lessons in composition.Denisov's cycle for soprano and chamber ensemble Le soleil des Incas (1964), setting poems by Gabriela Mistral and dedicated to Pierre Boulez, brought him international recognition following a series of successful performances of the work in Darmstadt and Paris (1965). Igor Stravinsky liked the piece, discovering the "remarkable talent" of its composer. However, it was harshly criticised by the Union of Soviet Composers for its "western influences", "erudition instead of creativity", and "total composer's arbitrary" (Tikhon Khrennikov). After that, performances of his works were frequently banned in the Soviet Union.
