This illustrated lecture is composed of elements from Aura Satz’s long-term research around sound, catastrophe, solidarity, and temporality. Her current works and feature film in progress reimagine emergency sirens in the age of man-made and ecological disasters. Working alongside several collaborators, from musicians to scientists to community activists, the project envisages the new sounds of emergencies that signal new disasters in times of climate collapse, and productive ways of operationalising them.
