Foster's concise analysis of art practices over the past three decades traces important models at work in art and theory, with special attention to the controversial connections between the two during this period. The author includes a new narrative of the historical avant-garde and concludes with an original reading of our contemporary situation--and what it portends for future practices of art, theory, culture, and politics. 90 illustrations.
