show me your second face

Akky and I went to the Tomoko Mukaiyama's concert in Amsterdam

"show me your second face" was
a good example of an advantage made in collaboration.

A skin changes to a dress and a house further.
The piano, singing voice, internal plucking strings.
It could be said that it was the performance shown your concern
about psychosomatic extensibility from the point of view of "inside and outside".

You might say I hope too much,
but I heard that electric sounds was sometimes interfering with the piano,
rather than efective, due to the idiomatic way of electronics.
The latest production, "haar" which I saw was better on that point, I think.
