The organ will sound like a whole orchestra - from a transparent whisper to a powerful tutti. Evgeny Avramenko, the titular organist of the Kaliningrad Cathedral, brings a solo program where Bach's Chaconne coexists with the French Romantic school and 20th-century music. The score of the evening is a journey through the registers, light, and shadow of a single instrument. An organ concert is always a conversation about time, space, and the breath of music. In Evgeny Avramenko's solo program, the organ reveals itself in all its possibilities: as an architectural structure, as an orchestra in one instrument, and as a subtle interlocutor capable of conducting an intimate dialogue with the listener. The first part of the program addresses the Baroque tradition and its legacy. Bach's Chaconne, in the arrangement by Michael Keller, is built on the relentless movement of the bass formula, over which increasingly complex and expressive variations grow. Here, the strictness of form is heard, and at the same time, an inner freedom - the music seems to test the limits of stability and return to a sense of support. Next, the organ speaks in another language. The works of Peeters, Uzandizag, and Gilman show how the instrument masters Romantic and post-Romantic imagery: the melody becomes more flexible, the harmony richer, and the sound almost pictorial. These pages require special precision and skill in working with register colors, where one movement can change the character of an entire episode. In the second part, attention shifts to 20th-century music. Arbatsky's Passacaglia and the compositions of Blarr and Karg-Elert open another dimension of organ sound - philosophical and contemplative. Here, external effect is not important, but the slow unfolding of thought, where every pause and every repetition matters. Where to go in St. Petersburg can be found on our website.
