The choir has collaborated with numerous orchestras, including the NOSPR orchestra under the direction of Gabriel Chmura, performing Benjamin Britten’s ‘War Requiem’ during the Wratislavia Cantans International Festival. A significant achievement was the performance of ‘The Passion According to St. Luke’ under the direction of Maestro Krzysztof Penderecki, as well as ‘Credo’ by K. Penderecki under the direction of Maciej Twork. The choir’s high level was appreciated by composers such as Józef Świder and Henryk Jan Botor, who dedicated their works to PCSN.
