To say that ballet is the foundation of dance is like saying that French Cuisine is the foundation of food.
I would guess that every famous painter, dancer, author, i.e., artist was derided as terrible by some authority or the authorities of his or her time when s/he first came on the scene. “Howl” by Ginsberg was thought to be horrible and people tried to have it banned. Van Gogh never sold a painting in his lifetime. Elvis was hated by parents for his pelvis. The Rite of Spring caused a riot.
But now all of those artists are famous, lauded, canonized. The works haven’t changed. The context changed.
Therefore, all work is worthy of praise and deserves to be canonized.
All that needs to be changed is the context.
Therefore, do whatever the %#!?+ you want and wait for everyone else to catch up.
And assume it’s perfect!

All three events are small bit of choreography that can be done inside the larger frame of contact improvisation.
