John Cage: A Mycological Foray' draws readers across the idiosyncratic, mushroom-suffused, innermost landscape of celebrated American composer John Cage. Upon the remarkable journey with Cage, one encounters assorted photographs, compositions, and contemplations; all in the very same unexpected fashion one encounters various flora and fungi species while mushroom foraging. Volume I encompasses Cage's mycological-oriented indeterminacy stories, diary excerpts, and essays; and the complete transcript of Cage's 1983 performance, 'Mushrooms et Variationes'. Volume II offers the inaugural reproduction of Cage's 1972 portfolio, 'Mushroom Book'; authored in collaboration with illustrator Lois Long and botanist Alexander H. Smith.
