Between 1967 and 1970 Italian auteur Giovanni 'Tinto' Brass directed four feature films in London, each starring a woman as the main character. Exploring the political, cultural and sexual ideas of their time, often in a deliberate pop-art style, they contain much priceless footage of now forgotten neighbourhoods, galleries, clubs and events as well as an abundance of contemporary music. Free Your Mind! describes the films, their stars, how they were made, and their influence on the social history, pop culture, cinema, music and TV of the time.
