“...Veléz's works are not mobiles, but their shapes make them look as if the sculptures are growing, even flying, like a plant has its roots firmly fixed in the ground, and yet its branches and leaves grow slowly toward sky until its seeds burst open, high and far. Entwining elegant lines, the thin, light sculptures depict Velez's particular way of creating tridimensional shapes. From every angle, their forms are seamless and lines, dynamic; their shapes change when light changes, giving the spectator an infinite, pleasant possibility of viewing the pieces...His work stands for the importance of three‐dimensionality, which is the foundation in sculpture. The forms can be observed continuously from any angle and the movement of the solid lines changes from shade to sun depending on the lights”. Kaoru Kato, Researcher of Latin American art / Professor Kanagawa University, Japan.
"Gustavo Vélez is like his works: young and full of that energy that waits only to find a form in his sculptures. He is nourished by a healthy enthusiasm for creating and by a strong passion for sculpture, which easily can be seen translated into his works, that seem that almost hardly are able to contain this unrestrainable creative fluidity. So Vélez passes from the cubic presence, almost just a modulated block of marble, to the slenderness of a cane: it rules the thinness and the mastery in educating the stone, the bronze, the steel. Skill, capacity, resoluteness, vision, all of this translated thanks to the hands of an artist, who insists in taking care of the form and of all its details. It remains the infinite, still to be explored, still to be transmitted, in this game of fixed points and mobile plans, between earth and heaven.” Valentina Foguer, Cultural Curator and Director of Pietrasanta, Italy.
