Avant-garde filmmakers have long explored the potential of cinema to afford a visionary experience, exploring the affinities of film with trance, ritual, dream and memory, testing the play of light on the depths of the subconscious. Curators Kathryn Siegel and Sophia Satchell-Baeza’s programme Sisters of the Extreme brings together a series of films by women from the 1960s to the present day, concentrating on work that shares an occult sensibility and a concern with film’s potential to render heightened mental states, from the meditative to the ecstatic.
