The image of Yves Kleins leaping into the void captures all that was ironic, serious, conceptually driven, and courageous in its free fall, of the contemporary art world of the 1960s and 70s. Nuit Banai shows how Kleins very brief working life as an artist just eight years came into being and how his signature works such as his living paintbrushes, monochrome paintings, and immaterial performances have became significant art historical markers for a generation of artists working today.
