She has always been an avangard conceptual artist. Most of her activities can be understood as event, action, happening, including that "Bed in - Love & Peace", "Cut Piece" and so on. She says that is something you can experience the idea or make yourself free from senses by doing it or imagining you are doing it. But I wonder if it has any value while most of ordinary people don't understand those, such as screaming music or plane weird events.
