On March 23 and 24, 2023, the musical work “Kanon Pokajanen” by the Estonian composer Arvo Pärt was performed at St. Nicholas Patriarchal Cathedral in New York. The work was presented by the combined Hosanna choir of the Russian Church Outside of Russia. The choir members learned the score for about two months while living in different cities across the USA and met for a joint rehearsal two days before the performance. On the second day, March 24, the First Hierarch of ROCOR, Metropolitan Nicholas of Eastern America and New York, and Archbishop Gabriel of Montreal and Canada came to hear the choir. Before the concerts, the guests were greeted by the rector of St. Nicholas Cathedral, Archpriest Igor Vyzhanov. After the performance, fellowship between the performers and listeners continued at a reception organized by the choir in the parish hall.
