Featuring works by Francisco Goya, Sergei Eisenstein and Robert Longo, Proof offers insight into the singularity of vision through which artists can reflect the social, cultural and political complexities of their times. Spanning eras and continents, each of these artists witnessed the turbulent transition from one century to another, experiencing the seismic impacts of revolution, civil rights movements and war. While Goya served church and king, Eisenstein the state, and Longo emerged during the rise of the contemporary art market--the dominant benefactors of each period--they all rose to prominence through developing nuanced practices that challenged expectations. With commissioned essays by journalist, activist and author Chris Hedges, artist Vadim Zakharov and Garage Chief Curator Kate Fowle, plus an interview with Longo, this book is published to accompany the exhibition of the same name.
