Saxophone, piano, history, and experiment - everything will converge in one evening where improvisation will become a true musical exploration. At the Sergey Kuryokhin Center, a new series of musical events is launching, exploring the nature of free improvisation. The first evening will combine a lecture and a concert in one space, where the boundaries between word and sound will blur right before the audience's eyes. The program will open with a lecture titled "A Brief History of Free Improvisation in Soviet Russia," delivered by saxophonist Sergey Letov - one of the prominent figures of the domestic avant-garde music scene and a participant in the legendary "Pop Mechanics" of Kuryokhin. Letov is known for his wide palette of expressive means: he plays not only the saxophone but also flutes, bass clarinet, ethnic wind instruments, wind MIDI controllers, and even instruments of his own making. Following the lecture, there will be a musical performance in duet with pianist Yaroslav Kovalenko. The joint improvisation of the two musicians will not be an illustration but a continuation of the theoretical conversation, embodied in sound. This is a rare opportunity to observe how an idea transforms into a living, evolving musical canvas over time. Yaroslav Kovalenko is a composer, founder of the Mader Nort association, and curator of academic music directions at the Center for Contemporary Art. His creative language balances between classical school and experiment, making him an ideal partner for such a performance. This evening is worth attending for those interested in the history and theory of music, passionate about live sound and its philosophy, and valuing the dialogue of formats. Here, academic thought meets creative spontaneity, and the audience has the opportunity to hear and contemplate not only the result but also the very process of music's emergence.
