Ever since Adolfo Estrada (Buenos Aires, 1942) arrived in Madrid in 1962, it has been impossible to imagine the Spanish artistic panorama without the important contribution of his silent «mystical geometries». Estrada's art flees from any decorative petulance and is condensed in pure formal asceticism, which is nothing less than the refined language of the essential. But this language is always both poetic and musical simultaneously, leading Francisco Calvo Serraller to describe Estrada's work as «the combined ars, the suite, the fugue, the harmonious creation of variations, a little in the manner of Bach».
