On the occasion of his 80th birthday, Die Schachtel is proud to present "Punctum Contra Punctum", a deluxe compact disc box dedicated to Aldo Clementi, one of the most important figures of Italian music of the 20th Century. Born in Sicily in 1925, he studied piano and later composition under the guidance of teachers such as Goffredo Petrassi and Bruno Maderna, who also introduced him to electronic music at the RAI Studio of Phonology in Milan.
