Nikolai Roslavets
Nikolai Andreevich Roslavets (4 January 1881 [O.S. 23 December 1880] – 23 August 1944, also Mykola Andriiovych Roslavets) was a modernist composer active in the Russian Empire and later the Soviet Union. Roslavets was a convinced modernist and cosmopolitan thinker; his music was officially suppressed from 1930 onwards.
