At TSEKH *, an exhibition opened about Soviet experiments where sound was attempted to be turned into light, and light into music. This is a look at the USSR as a space of early media experiments, when the synthesis of sensations was just being sought - at the intersection of art, science, and engineering. At the center are works from the student design bureau "Prometheus" and a circle of authors who created light-music instruments in the 1960s-80s and showcased them at festivals across the country. Here you can see how such devices worked: the "Disco" installation projected color directly onto walls and was even used in factory break rooms, while the "Crystal" with hundreds of lamps was controlled by pedals and keys, like a full-fledged instrument. A portable light artist's device turns hand movements into living abstraction, while systems like "Yalkyn" collect images from light, reflections, and rotating stencils. A separate block is dedicated to cinema and sound: black-and-white film was hand-painted, and multi-channel acoustic systems allowed sound to be moved through space using light. All of this is an attempt to literally "stitch" different feelings into a single experience, long before digital technologies. A modern installation from "dreamlaser" continues this conversation in the language of today's technologies, engaging the viewer in the process. The project is part of the "INTERVALS" festival program and offers a chance to see how art of the future was constructed in the USSR - with hands, lamps, and sound.
