This video is excerpted from the Season 5 episode Systems premiering on Wednesday, October 28, 2009 at 10pm (ET) on PBS (check local listings). Systems features four artists—John Baldessari, Kimsooja, Allan McCollum, and Julie Mehretu—who invent new grammars and logics, finding comfort in some systems while rebelling against others in today’s supercharged, information-based society. John Baldessari was born in National City, California in 1931; he lives and works in Venice, California. Synthesizing photomontage, painting, and language, Baldessari’s deadpan visual juxtapositions equate images with words and illuminate, confound, and challenge meaning. He upends commonly held expectations of how images function, often by drawing the viewer’s attention to minor details, absences, or the spaces between things. By placing colorful dots over faces, obscuring portions of scenes, or juxtaposing stock photographs with quixotic phrases, he injects humor and dissonance into vernacular imagery. For most of his career John Baldessari has also been a teacher. While some of the strategies he deploys in his work—experimentation, rule-based systems, and working within and against arbitrarily imposed limits to find new solutions to problems—share similarities with pedagogical methods, they are also intrinsic to his particular world view and philosophy.
