Michael Le Grice, a pioneer of 'structural film' in the 1970s and whose first video and computer works were exhibited in the late 1960s, provides a collection of his most notable essays. The essays shed light on the work of other artists and film-makers and documents a period, especially the 70s, when artists' film was at the centre of polemical debate about the nature of avant-garde and the future of radical or experimental film. The book contributes to the contemporary debates about film, video, art and new technology.
