This book gathers together a group of international artists, architects, scenographers, performers, and theorists to establish Performance Design as a fluid and emerging field, which explores the speculative and projective acts of designing performance and performing design. The theoretical essays and realised projects offer a lively and stimulating range of performative expressions across disciplines, where design artefacts -- objects, gestures, images, occasions and environments -- are aligned to performance through notions of embodiment, action and event. Performance Design is presented as an aesthetic practice that harnesses and orchestrates the dynamic forces of the lived world, as well as the participatory role of a co-creative audience, to provide a critical tool for reflecting, confronting and realigning worldviews.
