Andrés Sobrino (San Miguel de Tucumán 1967) works with his materials as a collector: he separates them, classifies them by color, shape and texture and then intuitively rejoins them. He searches through the different combinations for an image that imposes, so that the cross between different materials finally emerges the unexpected. Objects that come from his surroundings, the street and the workshop, from the "copper octagonal chocolate box background" to a "mosaic found on the road by my daughter Helena". In front of the material, the first thing that appears are the shapes. His fascination focuses on the experience of geometry. Triangles, circles and cubes predominate, resulting in more complex figures such as hexagons and trapezoids. Simple and well-differentiated shapes: "a square is not intended to be a circle", it is read in one of its notes. In addition to formal, his search is pictorial. Sobre Block. This collection allows us to know the processes of production and thought of contemporary Argentine artists. In each book an artist presents a thematic axis of research through sketches, annotations, images of works and writings. Thus these visual essays allow us to understand in the way of working of each of the authors letting us see the behind the scenes of their creation.ʺ (HKB Translation) --Colophon.
