The themes, debate, and curatorial perspective are explored through three new essays by Christine Eyene (curator and author), Cathy Lane (sound artist, composer and professor of Sound Art at the University of the Arts London) and artist and author Salomé Voegelin (author of The Political Possibility of Sound, Bloomsbury). The definition of Sound Art has always been narrow, from the perspective of gender, and international cultures. The book widens and rebalances the understanding of the art form and embraces the rich vein of work that needs to be a part of a new history of this creative practice.
