Kirthi Nath’s short videos include a few keenly felt moments. But her pastiches of the personal and the poetic—technical explorations and autobiographical fragments, phone messages accompanying on-screen texts and offhandedly composed imagery—can be simply incoherent. One of the better pieces, Letting Go (2005), consists mostly of black-and-white stills of a single apartment; the grainy images of sometimes empty spaces can be evocative, but fragments of voice and amateurish music turn it into a mess. By the By (2004) shows an airport terminal and Indian streets in footage as seemingly uncontrolled as the soundtrack’s mix of emotionally charged phone messages from “mom” and nearly incompetent music. 57 min.
