Aldo Clementi (25 May, 1925 - 3 March, 2011) was the last survivor of the great generation of Italian postwar musical avant-gardists. He was also its quietest and most self-effacing member, both personally and musically. After a hesitant start, he developed a technique that allowed him to produce works as calmly consistent in sound and technique as a Renaissance motet, and some would say just as beautiful.

Krzysztof Penderecki (born November 23, 1933 in D?bica) is a Polish composer and conductor.
