The ensemble "Blagovest" and children's choirs from Moscow will gather in the Chamber Hall to introduce listeners to the spiritual world of Mozart's music. The organ colors and the lively narration of Anton Viskov turn the concert into an understandable and captivating encounter with choral masterpieces that resonate with faith, doubt, hope, and gratitude. Mozart's spiritual music sounds especially poignant when entrusted to children's voices. This feeling is the foundation of the program of the ensemble "Blagovest," which unites a professional group and choirs from Moscow schools. Together, they demonstrate that complex choral compositions can be lively and relatable for teenagers and parents accustomed to a completely different sound environment. The concert is structured as a grand story about a person for whom the choir was the main source of inspiration. Anton Viskov leads the evening as a conversation with the audience: he explains how spiritual hymns differ from masses, why a composer needs an organ, how polyphony is structured, and why it is important to listen to it precisely "here and now." Detailed comments help to follow the development of the music and better understand the images embedded in the score. The choral groups "Cantilena" and "Pervotsvet" perform alongside adult singers. For the young participants, this is a serious professional experience, and for the listeners, it is an opportunity to hear how children's voices reveal the themes of faith, hope, and gratitude. Combined with the organ and ensemble, a rich sound emerges, where both the temple structure and concert energy are heard. The ensemble "Blagovest" has been working for many years with spiritual repertoire from different eras and styles. Its programs feature major works by Russian composers, European spiritual tradition, and chamber choirs that rarely appear in conventional philharmonic programs. This experience allows musicians to treat the texts with care, while not losing the vital impulse and dramatic tension necessary for today's listener.
