New technologies radically challenge the traditional position of the listener and its infrastructure but also, the composers and musicians and the technologies they employ. First, concert halls, opera houses, theaters and other performance spaces are architectural landmarks in many towns and cities. They offer spaces where communities meet and share meaningful experiences. Therefore, in this use case artists in collaboration with technologists, scientists, architects and designers will explore new ways of designing musical and dance performances as well as interactive, performative spaces and environments, both physical and XR-enhanced by using audience interactivity as a medium for generating sonic material.
