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. His 1960 avant-garde Threnody to the Victims of Hiroshima for string orchestra brought him to international attention, and this success was followed by acclaim for his choral St. Luke Passion. Both these works exhibit novel compositional techniques. Since the 1970s Penderecki's style has changed to encompass a post-Romantic idiom.
