Michael Snow, artist. Internationally renowned multidisciplinary artist Michael Snow (b. 1928, Canada) visited the National Gallery of Art on February 8 and 9, 2014, to introduce two programs of his influential experimental films. The four titles included—Wavelength (1966), So Is This (1982), Back and Forth (1969), and One Second in Montreal (1969)—all consider the astonishing, but often unrecognized, effects of light, memory, and duration on perception. Michael Snow introduced the program, and graciously took questions from the audience.
