‘RATBAG: A Solo Deviser’s Journey’ explores the use of solo devising as a method for gathering, exploring, and theatricalising autobiographical memory, culminating in the creation of a performance titled ‘RATBAG.’ Through a detailed process of self-reflection, interviews, and practical experimentation within the rehearsal space, the research investigates how personal narratives can be transformed into performative expression. Central to this exploration is the concept of ‘The Spark,’ the initial moment of inspiration that drives creative exploration and the utilization of ‘distractions as tools rather than obstacles’. By embracing a non-linear, intuitive approach to devising, and by incorporating multimedia elements such as video projection and soundscapes, the researcher delves into the complexities of memory and its distortion over time. This study also addresses the ethical considerations of using personal and familial histories in artistic creation, emphasizing transparency and consent. Ultimately, this dissertation provides insights into the solo devising process, revealing its potential as a deeply personal and transformative and potentially therapeutic approach to creating autobiographical theatre.
