On May 19, 2023, an international choral master class was held in the parish hall of St. Nicholas Patriarchal Cathedral in New York. It was led by Vladimir Gorbik, conducting teacher at the Moscow State Tchaikovsky Conservatory, choir director of the Moscow Metochion of the Holy Trinity-St. Sergius Lavra and member of the Grammy jury. Under his direction, the clergy, choir directors and singers of the Patriarchal Parishes in the USA and the Russian Church Outside of Russia honed their choral skills for three hours. Before the event began, the participants were greeted by the rector of St. Nicholas Cathedral, Archpriest Igor Vyzhanov.
