At Expo Milano 2015, Lamassa has created a project to celebrate the 70th anniversary of the explosion of the first atomic bomb on the Japanese city of Hiroshima. To remember the publication of the article on Il Corriere della Sera on  August 8, 1945 reporting the event, the curator and director of Il Rivellino Arminio Sciolli and the journalist Carlo Baroni decided to invite Michele Lamassa to the weekly cultural program of CasaCorriere. This allowed the visitors to appreciate an artistic technique that has apparently become obsolete: the artist of Italian origins, is famous on the international artistic scene for his works inspired by the fresco and “detachment” painting technique, which Michele Lamassa used to create a vibrant and communicative work that will be exhibited for the entire week. Michele Lamassa’s language is an introspective expression of the artistic perception of space, an elaborated and complex art to be performed slowly that allows for a conversation between the material component of lime, the colors of natural pigments and the human sensations.
