End of summer he participated at the Concert For Viareggio as the only sculptor, with 5 of his works beneath the stage. The idea came from Zucchero “Sugar” Fornaciari, the headliner of the evening along with many other artists and celebrities from the worlds of sport and entertainment.

In occasion of the Teatro del Silenzio,the worldwide famous Andrea Bocelli concert ,which took place on July 25th 2010 ,he created the stunning 14 meter monumental sculpture of a modernistic star as well as the metallic human figures in bright crayola colors that peopled the stone walls of the openair theatre, and also graced the rooftops and piazzas in Lajatico.

His opinionated sculptures are made of materials that are heavy, but seem to be light when seen in the definitve work (Marble, Bronze, Iron, Aluminium). Sometimes, the materials are bare, but often they are painted unicolored with a rather violent color.
