The Routledge Companion to Remix Studies, 2nd Edition comprises contemporary texts by key authors and artists who are active in the interdisciplinary field of remix studies. As an organic international movement, remix culture originated in the popular music culture of the 1970s, and has since grown into a rich cultural activity encompassing numerous forms of media. The act of recombining pre-existing material continues to bring up pressing questions of authenticity, reception, authorship, copyright, and the techno-politics of media activism, especially with the emergence of artificial intelligence, which relies on remix methods and principles for content production. This book approaches remix studies from various angles, including sections on history, aesthetics, ethics, politics, and practice; and offers theoretical chapters alongside case studies of remix projects. This second edition includes ten new chapters, and nine revised chapters. Reprinted chapters from the first edition are updated with editorial prefaces. This volume offers in-depth insight for long-term relevance among the many interdisciplinary fields that rely on and also contribute to remix studies. This companion is a valuable resource for both researchers and remix practitioners, as well as a teaching tool for instructors using remix practices in the classroom.
