Focusing on staging processes in contemporary dance and art performance creates new opportunities to study creative participation and co-authorship. To gain these new insights, Iris Julian analyses experimental projects initiated by two groups and a single choreographer: Collect-if by Collect-if, Deufert + Plischke and Xavier Le Roy. By exploring nuances of staging work, the concept of singular plural became the analytical guideline and resulted into three research perspectives: theatre studies, sociology and ontological reading (Jean-Luc Nancy, Michaela Ott, Gerald Raunig). This approach makes it possible to look beyond the importance that is often credited to single authorship in the arts. With a foreword by Prof. Dr. Gerald Siegmund.
