Produced out of Harvard’s Sensory Ethnography Lab, Laura Huertas Millan’s masterful La Libertad follows a group of matriarchal weavers in Mexico, whose backstrap loom – a pre-Hispanic technique preserved for centuries by Indigenous women in Mesoamerica – provides the formal structure for the film’s exploration of handicrafts and their ties to freedom. With echoes of the influential ethnographic work of Chick Strand, La Libertad combines astute observation, testimony, subtle transfers in scale, space and texture, as it weaves its own singular study of labour, creativity, and the mysterious traces that circulate between them
