Lydia Ourahmane is an Algerian-born multidisciplinary artist who has spent much of her life in the UK. In her installations and interventions, the notions of object and subject—considered separate in Western thought—converge and dialogue between the public and private, the alien and borrowed, migration and extractivism, everyday life and the affective materiality of things. In this podcast we talk (in total darkness) to Lydia about her relationship with echo as a phenomenon for the creation of negative space, about listening as a trigger for singular experience. We also talk about her connection to spirituality through her family experience, a community persecuted for its faith in her home country. Finally, we hear some open questions about the idea of home, belonging and freedom, and about the miraculous, the unexplained and the absolute.
