Action Space was formed in 1968 by a group of artists who had become disillusioned by the commercial gallery system. The group lived communally and took over a derelict piano factory in Harmood Street in Camden which became a licensed squat. Their philosophy was firmly rooted in education and creative play, with a belief in the potential of creativity to implement social change. Action Space's Air Structures were huge inflatable installations which involved soundscapes and performances by an array of costumed artists, theatre practitioners and musicians. Their work was truly pioneering and radical in scale and ambition. Follow this link for an account by one of its founding members, Ken Turner.
