Bound in a tête-bêche format as a reversible book with two front covers, Urs Fischer: Yes documents two iterations of the ongoing collaborative project of the same name orchestrated by Urs Fischer (born 1973), which has brought together thousands of collaborators from all walks of life-schoolchildren and adults, artists and amateurs-to make objects out of clay. Yes has populated numerous locations with clay figures, including the warehouse-like space of the Geffen Contemporary at The Museum of Contemporary Art, Los Angeles, and the sun-washed terrain surrounding the Deste Foundation's project space in a former slaughterhouse on the Greek island of Hydra. In this volume, installation photographs from both locations capture what entropy adds to the project: the unfired clay sculptures disintegrate over time, creating continuously changing landscapes of fragmented, crumbling forms.
