Book excerpt: The essays in this collection explore the extraordinarily rich networks of international artists and art practices that emerged in and around London during the 1960s and ’70s, a period that saw an explosion of new media and fresh attitudes and approaches to making and thinking about art. The contributors to London Art Worlds examine the many activities and movements that existed alongside more established institutions in this period, from the rise of cybernetics and the founding of alternative publications to the public protests and new pedagogical models in London’s art schools. The essays explore how international artists and the rise of alternative venues, publications, and exhibitions, along with a growing mobilization of artists around political and cultural issues ranging from feminism to democracy, pushed the boundaries of the London art scene beyond the West End’s familiar galleries and posed a radical challenge to established modes of making and understanding art. Engaging, wide-ranging, and original, London Art Worlds provides a necessary perspective on the visual culture of the London art scene in the 1960s and ’70s. Art historians and scholars of the era will find these essays especially valuable and thought provoking. In addition to the editors, contributors to this volume are Elena Crippa, Antony Hudek, Dominic Johnson, Carmen Juliá, Courtney J. Martin, Lucy Reynolds, Joy Sleeman, Isobel Whitelegg, and Andrew Wilson.
