This performance-as-research project documents, both through linguistic and non-linguistic texts, an investigation of the materiality of performative knowledges and analyses Music Theatre as an ecstatic and hyper-erotic creator of these knowledges. By actively engaging in a performative translation of an historical Music Theatre work, this research investigates how ecstatic inscription creates materiality within the performative knowledges of Music Theatre, and aims to provide further substance to the discourse surrounding performative knowledges and their relation to the epistemology and methodology of performance-as-research.
