T. J. Clark, George C. and Helen N. Pardee Chair and professor of history of art, University of California, Berkeley. Centered on a group of paintings by Picasso from the 1920s, a series of six lectures traces the artist's path to Guernica. In this audio podcast of the fifth lecture, originally delivered at the National Gallery of Art on April 26, 2009, the renowned art historian and professor T. J. Clark looks at Picasso's attempts in the late 1920s to escape from the room-space of cubism into a wider public world, populated by monsters (comic or tragic, benign or terrifying) on a grand scale.
