This is a painting we realized on commission in january 2013. It's an indoor painting made on two different floors connected by stairs. It's impossible to see it for entire without moving, because of the structure of the place, and so becomes suggestive the moment when someone walks upstairs or downstairs, perceiving two different moods and two different situations. Discovering step by step that the percentage of oxygen is changing, and that it ts proportionate to the volume of the notes of the song of the whales.
