Set to Jean Sibelius’s “Karelia Suite, Op. 11” (1893) as requested by Richard Tuttle, Madeline Porsella’s sixteen-minute video “What Is the Object?” is a meditation on color, sound, shape, and touch, even if only implied. For those who have already seen the exhibition, this video adds the dimension of sound; to those who have yet to visit, it prepares them for a haptic encounter.
