It is the first book on arts-based research which focuses on the city, adopting a posthumanist approach to the assembled nature of urban environments, where agency is distributed across infrastructures, technologies, spaces, things, and bodies. Chapters one to seven feature a series of studies, situated in different cities in Europe and the Americas, which outline experiences of movement, inhabitancy, interdependence, collaboration, infrastructuring and sensorial re-calibration informed by art practices in film, photography, digital projection, installation, performance and art as social practice. At the core of this book is the idea that aesthetic ecologies of cities do not depend solely on human activity, relying instead on non-logocentric modalities of collective life. The book is an indispensable tool to researchers, instructors and graduate students in education, the social sciences and the arts aiming to conceive, design and develop projects in arts-based research.
