Hermann Nitsch
Architect of the Orgien-Mysterien-Theater — the total, ongoing ritual that outlived the group as its own theatre.
Otto Muehl
Pushed the Action toward the collective body; would later found an ill-fated commune.
Günter Brus
Turned his own body into the surface pushed to violent extremity — self-painting into open transgression.
Rudolf Schwarzkogler
The one whose death, in the early years, was mythologised around the group forever after.
