The oldest festival of the Cathedral - "Masterpieces of World Classics in the Cathedral on Kant Island" - has been traditionally held in October and November for 17 years. The festival includes not only concerts but also entire "laboratories." Audiences can expect solo concerts by laureates of the XIII International Organists Competition named after Mikael Tariverdiev, performances by opera singers in duet with the organ, unusual instrument combinations, the ceremony for the All-Russian "Organist of the Year" award, Philosophy Day, and much more.
