George Cacioppo was an American composer. After studying chemistry and music at the University of Michigan (UM), he completed a bachelor’s degree in music and a master’s degree in composition in June and August 1952 respectively. Cacioppo was awarded a Koussevitzky grant to study at Tanglewood in 1959 and was one of the founders of the avant-garde once festivals, which began in 1961. He was a visiting lecturer in composition at UM (1961–68 and 1979–80) and produced and hosted the “New Music” program on radio WUOM/WVGR. Cacioppo experimented with novel forms of notation in works such as Advance of the Fungi, an orchestral piece from 1964, and, most notably, the piano work Cassiopeia (1962).
