Hi, I discovered one more quote that adds weight to your argument. “IN PERFORMANCE ART EVERYTHING IS REAL: THE EXHAUSTION, THE BLOOD OR THE KNIFE. THERE IS NO ACTING. IN THEATRE, BLOOD IS KETCHUP; IN PERFORMANCE IS REAL BLOOD.” -- Marina Abramovic, from her website (2016): https://mai.art/as-one-content/2016/4/5/highlights-from-marina-abramovic-first-workshop
