For Piccinelli the wall as an element of architecture; represents a formal geometric visual structure on which appears the traces left by man (which is similar to the research of the painter Antoni Tàpies) It is the informal part and random which expresses the spirit; the heart; the time and the emotion. We can say that Piccinelli; in this series; revisits the codes of Street Art within his research towards a minimalist abstraction."We could say that we find what separates Mangold from Scully in the distinction established during the Renaissance between" disegno "(drawing) and" colore "(color) or in the opposition between gestural painting (Pollock) and field of color (Newman) in Abstract Expressionism.Tony Godfrey; "Painting Today" Phaïdon Edition; 2010.
