The principal members of the group were Günter Brus, Hermann Nitsch and Rudolf Schwarzkogler. Their ‘actions’ were intended to highlight the endemic violence of humanity and were deliberately shocking, including self-torture, and quasi-religious ceremonies using the blood and entrails of animals. Nitsch gave his ceremonies the general title of Orgies-Mysteries Theatre. A less violent but no less anguished Vienna action artist of the time was Arnulf Rainer.
In America Dennis Oppenheim, and in Britain Stuart Brisley, performed actions in a spirit that can be related to Wiener Aktionismus.
