Drawing from Dinesh's findings in Memos from a Theatre Lab: Exploring What Immersive Theatre "Does", this practice-based-research project - second in an envisioned series of Immersive Theatre experiments in Dinesh's theatre laboratory -- considers the potential impact of pre-existing relationships between actors, spectators, and performance spaces when using immersive theatrical aesthetics toward educational and/or socio-political objectives. Memos from a Theatre Lab: Spaces, Relationships and Immersive Theatre explores the following questions: When audience members do not know the actors outside the milieu of a theatrical performance, does an immersive form hold different implications than if performers and spectators know each other in 'real life'? When actors and spectators are strangers to each other, are performers more or less likely to judge the responses that are given to them within an immersive scenario? What kinds of immersive situations, especially in Applied Theatre interventions, might benefit from the presence or absence of a pre-existing relationship between performers, audience members, and the spaces in which these experiences occur? In describing the processes involved in: designing such an experiment, crafting the relevant immersive performances, and gathering/ analysing data from actors and spectators, this book puts forward strategies for students, researchers, and practitioners who seek to better understand the form of Immersive Theatre.
