Dematté's art represents a turning point in the international artistic scenery. The techniques he adopts, the materials he chooses for his works, make this artist a tireless polyhedric explorer of new artistic representations. Inside an extremely multifaceted expressive language the explosive effect of a decisive aesthetic research is asserted, determined to get out of all the traditional creations. The spirit of the artist's investigation is already visible in the "Generazione" ("Generation", 2011) works group, in which we find an exhilarating abstract work made of enamels. Through an inherent design balance, the forms expressed through the chromatic black and blue contrast and animated by a clean white coloured background, seem to vibrate leaning beyond the structure that contains them. It is a search of concreteness in three-dimensional space which will be increasingly evident in his artistic career through the use of the collage technique. The work "Rilievi" ("Reliefs", 2011) is characterised by a strong aesthetic appeal. A candid scenario, composed of a soft fabric, animates vibrating ripples resembling body footprints. It is about energy waves freed from the sapid connotation of body physiognomy, that give the impression of leaping supplely from the canvas. Collage art has often accompanied last century's aesthetic movements, but with Dematté it takes on new features and different chances of expressions.

In the cycle of works "Costruzione" ("Construction", 2012) this technique is used with absolute mastery aiming at creating an artistic composition which is completely detached from the two-dimensionality of the canvas to flow towards the reality of reality. Collage in these works becomes more and more a sort of miniature installation meant to host plastic materials which extend beyond the plane space of representation. Standing out in the artistic compositions "Costruzione" is a rich inlay of small woods chromatically exalted by white or black which, stuck in layers, through a completely autonomous expressive language, stand up from the two-dimensional surface, from which they are born in order to call to mind pure geometrical essences. The collages are built on white backgrounds. Such colour vigorously enhances the shadows of the materials of the composition, giving life to dark natural shapes that seem to become magnetic force fields aimed at supporting the material elements of the handwork, superimposed on each other. In Dematté's works we find the desire to explore three-dimensional space, but we also find a run back, depths, often to underline deep meanings related to human beings.

The collage process takes a new connotation which becomes more and more radical in the work "Compressioni" ("Compressions", 2014). The selected items are not pasted on the canvas, but they are pressed inside a folder, isolated from world to enter the neutral space of art. Bags and bags for women, pressed by the artist through a refined positioning game, underline two overlapping photographs of different sizes, that highlight a bedroom and the gash of a female figure. Overall the folder becomes a window where you can see a domestic landscape and the handbags not only assume theatrical aesthetically stimulating contortions, but they also become coloured streaks, designed to animate and tell one of the usual aspects of daily life.

Starting from the surface, the alpha form of the artist's linguistic experiments, a series of many more expressive possibilities are declined, also poured into the realization of sculpture works. The complete absence of figuration and the adherence to a language which is part of the informal research channel of the second part of the 20th century, lead the artist to create sculptures which are vivified by original material.

In the series of sculptures "Evoluzione" ("Evolution", 2011-2012), woodn, a new generation composite wood, mainly used in architecture for interior and exterior coverings, changes into a sensitive element of artistic type. Woodn, placed on a delicate iron base, moulded through bands and eversions gives the impression to penetrate into the atmospheric environment. The aesthetic factor in these works is amplified by natural light, which shapes the modular forms of the composition, charging them with very pure creative energy which welcomes and reflects impregnated with shiny colours atmospheres. We also find modular beauty in the sculpture "Proiezioni" ("Projections", 2014).
