The great dilemma of the artist is that, by expressing an idea, by realising it, he is already distorting it. The deepest emotions are intangible, ethereal, abstract. Rosendo Porro Cuesta manages to give form to the anti-form, to express the inexpressible, the invisible. In an exercise of necessary humility, but with an extraordinary aesthetic power, he does not place us in front of an idea but in front of its shadow. Its essence, its heart, its trace. An empty piano, traced by its mere silhouette, is a perfect way of defining music: without the piano, music does not exist; and yet the important thing about music has never been the piano.
