Emptyset, James Ginzburg and Paul Purgas, explore both spatial and physical properties of sound; specifically the perceptible boundaries between it and noise. They have produced installations for Tate Britain and the Architecture Foundation in London. Emptyset"s new album Dissever continues their exploration of the histories of 20th century electronic sound and media. Dissever delves into the intertwined evolution of cosmic rock, minimalism and electronic music, viewed through their prospective dreams and overlapping technological ambitions. Premiered at Tate Modern as a live performance, Dissever was part of the exhibition Electric Dreams, a large-scale survey of the global history of art and technology. The resulting album is astoundingly sublime, rich with sonics that are as thrilling and immediate as they are singular and dense with complexity.
