THE FOURTH DIMENSION is an elegant meditation on time, travel, and ceremony in the form of a journey. In her first foray into digital video, Minh-ha deconstructs the role of ritual in mediating between the past and the present. She explains, “Shown in their widespread functions and manifestations, including more evident loci such as festivals, religious rite and theatrical performance, ‘rituals’ involve not only the regularity in the structure of everyday life, but also the dynamic agents in the world of meaning.” With its lush imagery, Minh-ha’s Japan is viewed through mobile frames, with doors and windows sliding shut, revealing new vistas as it blocks out the old light.
