BILBAO, SPAIN – The year 2011 marks the centenary of the birth of Roberto Matta, one of the most significant figures in twentieth-century art because of his importance as a member of the Surrealist group and his enormous influence on the development of American Abstract Expressionism, and above all because he was an absolute artist, a visionary and a precursor of the relationships of art, science and nature and the fundamental role of art in the complete development of the human being.
