Chamber music will sound like a conversation of souls: nearby is the piano of Nikolai Lugansky and the delicate violin line of Nikita Borisoglebsky. Brahms will meet and the rare "transformation" of the sextet into a trio format, and then - a dense piano quintet, where the tension rises from measure to measure. An evening of chamber classical music, where the stage turns into a circle of close interlocutors, and meaning is born from details. At the piano is Nikolai Lugansky; nearby are Nikita Borisoglebsky and Elena Tarosyan (violins), Andrey Usov (viola), and Alexander Knyazev (cello). This ensemble creates a rare effect of "living optics": you can hear how each part changes the overall picture - as soon as someone takes a step forward, the entire fabric of the music is restructured. The program features Johannes Brahms, a composer who knew how to combine passion and strict form. The concert opens with String Sextet No. 2, but in an arrangement for piano trio. In this "translation," familiar themes sound different: the lines become clearer, the rhythm sharper, and the dialogue between strings and piano more nervous and precise. You can literally follow how the melody passes from hand to hand, how the light and shadow change, and why Brahms is called a master of inner movement. Next is the Piano Quintet in F minor, Op. 34. This is music with character: it has both broad breathing and flashes of almost theatrical tension. The quintet holds attention through contrasts - from transparent episodes to dense, almost orchestral climaxes, when the strings sound as a single body, and the piano sets the impulse and gathers the drama. In the chamber format, nuances are especially noticeable: short pauses, "questions" and "answers," barely perceptible shifts in tempo.
