In this volume, Hans Ulrich Obrist elicits from New York art veteran Yoko Ono a portrait of her life and career that is unprecedented in detail. Across five interview sessions, Obrist quizzes Ono about her earliest works in visual art and music in Japan, her musical development in New York, her friendship with John Cage, her Fluxus days, the founding of the new state of Nutopia with John Lennon and her ongoing campaigns for world peace and human rights. Ono also recounts here the genesis of her installations and performances, so many of which have since become classics of their genre. Throughout these discussions with Obrist, in which architects and artists such as Rem Koolhaas and Gustav Metzger also participate, this icon of twentieth-century culture shows herself to be a generous and smart personality, and a multifaceted artist of enormous influence.
