Professor of design for the most prestigious Spanish companies for more than 10 years, Kastro dedicates his efforts in artistic creations oriented to avant-garde and novel environments of art, where his interventions and works are present in more than 40 countries. A great connoisseur and follower of currents of abstract expressionism in its first stage, one can appreciate in his works high degrees of tachismo and informalism and later find in his work a very different way of understanding current abstract art. Tireless researcher of materials and elements, depending on the moment and form he experiments on materials, textures and even structures that lead him to create pieces whose purpose is to transmit feelings and emotions.
