Circumscribing the Open Universe

Routledge, Dec 2, 2013
In his collection of five analytical essays, DeLio closely examines five open-form works by five composers - Cage, Feldman, Christian Wolff, Robert Ashley, and Alvin Lucier. The author links these composers by their aesthetic credo that artwork is not a fixed entity but a process, not a "circumscribed object" but a "circumscribing event." ... his essays are among the most extensive and finest analyses of open-form works ever written. DeLio's book is one of the few monographs devoted entirely to aleatoric music.
