To enter into Diego’s world is a unique and immersive experience. Wherever our gaze rests, we see the eyes of thousands of zoomorphic and anthropomorphic whistles observing us. Sometimes it is immediate, and you know you cannot leave without one; other times it is an interminable task to choose the most beautiful cuco to take with us. His creations can be so small as to be held in the palm of the hand, whereas others are gargantuan and only with difficulty can they be taken out of the workshop. The recurrent factor is sound; each of these artefacts can be brought to life with the breath and each has a unique tone due to the different sizes of the sound box. In short, each cuco and archicuco has its own identity which is expressed not only through its form and colour, but also through its voice!
