Collection of 18 editions of avant-garde compositions from the 1950's–1960's, including pieces by John Cage, Karlheinz Stockhausen, Morton Feldman, Maurico Kagel, and others. Most of the scores have unusual pictorial or graphic notation, for example scores designed to be read right-side-up and then upside-down (Komorous' Olympia) or graphical scores which can be "read" in an order chosen by the performer (Kasemet's Timepiece.) Some display enormous complexity, as in Kayn's Signals, while others are minimal and pictorial: Kagel's Himmelsmechanik consists of a series of scenery drawings with timed sound effects of wind and weather. Overall a very interesting overview of experiments in musical notation and compositional practice during the post-war avant-garde. Scores of varying sizes, the largest 11.5 x 17.5 inches; overall in fine condition, with a few with slight water damage.
