PSR-55, second opus of the PSR serie, is an immersion among the vestiges of human civilization in which a minimal and technological form of life flourishes and emerges. This world that saw the end of the Anthropocene vibrates to the sound of a new language, that of light. A grammar made of colors, pulsations and gradients takes birth here. The digital vocalizations of the machines are the new sound identity of these places. We are witnessing the beginnings of a renewed and ingrained life in which the era of man seems to be over.
