This richly illustrated volume brings together fresh insights into the changing urban space of Barcelona from the beginning of the twentieth century to the present day. The collection focuses primarily on the complicated relationship between environment, identity, and performance as they were seen, explored, and portrayed by countercultural and avant-garde artists and communities from the 1960s to today. Drawing crucial links between theory and practice, aesthetics and environment—and paying particular attention to the role of the avant-garde in challenging and disrupting dominant art forms and uses of urban space—Barcelona presents a variety of perspectives and approaches, drawing on art history, cultural geography, performance studies, and institutional critique.
