An unusual musical project will present its program for the first time on a large Moscow stage. The audience can expect a combination of children's choral singing and heavy metal. A chamber children's choir will take the stage, performing compositions accompanied by heavy sounds with elements of industrial, gothic, doom, and nu-metal. This format combines academic singing with the powerful energy of modern music. The concert will be complemented by an unusual story about children who use songs to contain evil forces, trapping them in audio cassettes. According to the plot, the more people listen to these recordings, the stronger the seal becomes. Guests can look forward to live performances, dark aesthetics, as well as themed souvenir products. Special ticket holders will have the opportunity to meet the artists after the performance, take photos, and receive autographs.
