Abstract Expressionism will forever be associated with the energy and vibrancy of 1950s New York. Artists injected a new sense of confidence in painting, experimenting with improvisation, spontaneity, and color. This bold publication and the major exhibition it accompanies seek to reevaluate the movement, making the case that far from being unified, Abstract Expressionism was in fact complex and ever-changing. This volume includes works by the most celebrated artists associated with the movement—not just Pollock, Rothko, and de Kooning, but also Kline, Newman, Still, Smith, Reinhardt, and Gorky. Sculptors such as David Smith and photographers such as Aaron Siskind are also represented. With texts by well-known experts in the field, this is a landmark publication.
