Music Space Architecture is an international, multilayered project created in 2018 by the music curator Sasha Elina and architectural photographer Yuri Palmin. At its centre is a Moscow-based festival that brings together commissioned musical performances, audio-visual installations, a film programme and an interdisciplinary conference. MSA gathers academic and artistic writings, reviews and other published materials into the online platform (lanching in December 2021), dedicated to identifying and investigating different areas of interaction between music and architecture, sound and space. MSA appeals to the domains of time and space in musical and architectural discourses, architectural acoustics, the dependence on (or avoidance of) numbers and, most importantly, the sensory experiences of the listener entering into a dialogue with space and sound. Ultimately, MSA strives to present differing approaches to synthesizing the inaudibilities of architecture and the invisibilities of music.
