This survey of video pioneer Nam June Paik’s work includes 60s abstractions with swirling patterns and oversaturated colors—all superficially impressive but visually muddled. Paik seemed more interested in mixing up art and life than in formal control, and in the 1992 Electronic Yoga, made with Jud Yalkut, a man in a yoga position has three video monitors arrayed above him—a playful suggestion that a video installation can also “do yoga.” The 29-minute Global Groove (1973) offers a prescient look at the horror of artistic globalization, blending bad rock, traditional music, words spoken by John Cage, and a nude performance by the Living Theatre into a mindless mishmash. 93 min.
