“Since the early 1960s the names of Mark Boyle an Joan Hill have never been far from the centre of avant-garde artistic activity in this country. In the forefront of spectator-participation ‘events’ and ‘happenings’, inventors of the liquid light show, they have consolidated their reputation with the extensive (and extending) series of works centred around their Journey to the Surface of the Earth.
