This practice-based PhD explores three interconnected subjects: novel approaches to staging the creative process, the aesthetic nature and role of metaphor, and the use of worldbuilding methods in the creation of audiovisual art. Relationships between process and product, and the agency of technology in intermedia composition are also explored. The submission includes a portfolio of four core compositions, 3 additional compositions, and a commentary. The commentary first defines and discusses the subjects named above in order to articulate the aesthetic intentions underpinning my work, placing my practice in an expansive artistic framework. The project both plots the trajectory and critically reflects on two key ways my practice has transformed across the PhD. Firstly, from small-scale concert projects to a nebular art practice including methods of website design, exhibition formatting, 3D modelling and printing, virtual simulation design, speculative engineering design, and long-form durational installation. And secondly, from a shift in focus from ‘staging the creative process’ – through metaphor creation – to ‘worldbuilding’.
