Лев Степанович Гурылёв

The father of pianist and composer Aleksander Gurilyov, Gurilyov was a violin player and kapellmeister in the orchestra of Count Vladimir Grigorievich Orlov, the younger brother of Catherine the Great, to which was owned according to the principles of serfdom. The majority of his life was spent on the Semenovskoye-Otrada estate, owned by the Orlov family, although several moves occurred. Due to the inherited musical aptitude in his son Aleksander, Count Orlov had the son sent to study under the guidance of Irish composer John Field for music composition, and Joseph Iosifovich Genishta for music theory.
He was most notably the contemporary of other late-baroque and early-classical, serf composers in Russia like Dmitry Bortniansky, Stepan Degtyarev, and Daniil Kashin.
