Thought you might be interested in some notes written by people from the Ukraine about this beautiful piece of performance art:
The most emotional part starts at 3:50 when she draws the face of the young woman and an envelope - obviously a letter telling her of his death, She draws tears on her face, the woman becomes old, then the image morphs into the monument of the unknown soldier - well known monument in Ukraine. The music changes from violin to a song about the soldiers who died in other countries but came back to their homeland as white cranes.
It's about a young couple in love. He goes off to war; she has a child, but the man dies in the war. At the end she writes "We'll be together always." (Another commenter translated the words she writes as "You are always near.") One of the songs is a well-loved song about dead soldiers who become white cranes - very emotional. In Ukraine 1 in 4 people died during World War II - likely everyone in the audience is personally connected to someone who died. Some of these people ( ~60 yrs old) could be those children who never knew their fathers because they died in the war.
