Grigorij Ivanovich Poljakov
Very little is known about him. He studied voice with I. Charov. He must have sung at the Stanislavskij and Nemirovich-Danchenko Theater in Moscow, since all his recordings are accompanied by that theater's orchestra, and since his Alfredo and Paris were praised for having been realized under Nemirovich-Danchenko's personal guidance. He seems to have been a good actor.
