Bach's work 'St. Matthew Passion' is not just a concert, but a profound spiritual experience. Two choirs, two orchestras, strong dramaturgy, and arias filled with emotion transform the music into a confession. 'Bach's St. Matthew Passion' is not just a musical piece, but a grand drama where every note is imbued with meaning, faith, and tragedy. This concert will be part of the XIII International Organ Festival 'Mariinsky' and will open to listeners the world of one of the deepest compositions in the history of music. Bach created his version of the 'Passion' as a rite, as a path of sorrow and spiritual purification, combining the words of the Gospel of Matthew, Protestant chorales, and the poetry of his contemporaries. The music unfolds like a true theatrical drama - with dialogues, inner monologues, comments, and choral exclamations that create an effect of complete presence. A characteristic feature is the use of two choirs and orchestras located in different parts of the hall, which enhances the sense of volume and dramaturgy. At the conductor's podium is Konstantin Rylov. The performance features soloists, the choir, and the symphony orchestra of the Mariinsky Theatre. The piece is performed in German with synchronized subtitles in Russian - thus it is perceived as a whole even by those unfamiliar with the original text. Each character - from the Evangelist to Pilate's wife - receives their line in the score, and the arias, as emotional comments, allow a glimpse into the soul of each hero. Particularly strong impressions are made by the chorales - ancient spiritual hymns familiar to every Protestant community of Bach's time. They create a sense of communion and transport the listener into the atmosphere of a live worship service. Special mention should be made of the alto aria 'Erbarme dich', one of the most touching and human musical prayers in history. The poster for St. Petersburg is available on KudaGo.
