Higgins was deeply involved in Fluxus and in his own ‘Something Else Press’, and coined the term ‘intermedia’ to describe his experimentalist work. He knew Huelsenbeck and Duchamp, and studied with Cage (they also hunted wild mushrooms together) and Cowell. Maciunas, both friend and collaborator, never forgave him for his independent publishing. He also collaborated with Johnson (a good friend), Brainard, Monk and Vostell, and corresponded with the Campos brothers, Spoerri, Vautier, Chopin and Heidsieck. Brecht sold his rubber-stamp collection to him. He called himself a composer — but not necessarily of music.
