As well as undertaking numerous live performances across the 1960s and ‘70s, Greenham also featured in a number of radio broadcasts on the BBC, KPFA & KPFK (USA), Radio France, Westdeutscher Rundfunk, Zürich, NCRV (Netherlands), Madrid and elsewhere. Across this period Greenham was engaged actively in a need to communicate her work and ideas, an attitude perhaps best summarised in her text Art and Communication (1965), where she wrote that ‘communication is the consideration and action of impelling an impulse or particle from source-point across a distance to receit-point, with the INTENTION of bringing into being at the receit-point a duplication of what emanated from the source-point.’
