Dal grigio di Blu a un Blu molto grigio

Bologna: between late evening on the 11th March 2016 and the morning of the day after, the famous street artist Blu erased all the works he had painted in the city in the previous 15 years. The murales were covered in grey in protest against an exhibition where some of his paintings previously removed from two abandoned buildings were to be exhibited. Blu, with this performance, would write a new chapter in his career, thanks to conceptual art and to Blu's gray, his masterpiece.
