Nikolai Borisovich Obukhov (Russian: Николай Борисович Обухов; Nicolai, Nicolas, Nikolay; Obukhow, Obouhow, Obouhov, Obouhoff) (22 April 1892 – 13 June 1954)[1] was a modernist and mystic Russian composer, active mainly in France. An avant-garde figure who took as his point of departure the late music of Scriabin, he fled Russia along with his family after the Bolshevik Revolution, settling in Paris. His music is notable for its religious mysticism, its unusual notation, its use of an idiosyncratic 12-tone chromatic language, and its pioneering use of electronic musical instruments in the era of their earliest development.
