Emptyset present ash — a new collection of sound experiments developed over the last three years and assembled in Bristol during summer 2023. The work draws on the project's roots in structural percussion and physical sonics, employing spatialised recording techniques and an array of analogue hardware,evoking the transformative and sculptural properties of sound. The release marks a return for the collaborative duo of James Ginzburg and Paul Purgas, following Ginzburg's work within the exploratory performance group Osmium and Purgas' extensive research into the history of India's first electronic music studio.
