Reuniting after last year’s Between the Temples, director Nathan Silver and star Carol Kane shift focus to the actress’ 98-year-old mother, Joy Kane—a music teacher and former dancer who lives with Carol on the Upper West Side, and who regales them (and us) with fascinating cultural histories and piano performances over the course of a single afternoon. Carol & Joy is a documentary replete with love, pain, and texture: a close-quarters view of artistic vocation, mother-daughter bonds, and two women’s journeys through one century and into another.
