Opera "Peter the Great" by Andre Grétry at the Helikon Theater The Helikon Theater, known for its noisy manners, led by the extravagant director Dmitry Bertman, offered another repertoire curiosity - a comic opera by the French composer of the late 18th century Andre Grétry about the Russian emperor-carpenter. With a masquerade, theatrical confusion, spoken dialogue, a magnificent overture, a large love duet, a small divertissement, characteristic arias, and without particularly intense action.
