This fascinating volume explores the theme of mutating and adapting media in its relation to theatre and performance. Bringing together international scholars and artists, the editors offer a comprehensive overview of the changing nature of theater, focusing on interactivity, corporeality, liveness, surveillance, spectacle, performativity, and theatricality. 'Bastard or Playmate' shows how dismantling the medium of theater has led to a fertile ground for new art. This wide-ranging and vibrant book provides an excellent guide for readers unfamiliar with the field of intermediality, as well as researchers and experienced theater artists.
