"John Cage (Los Angeles 1912-New York 1992), by many considered the most influential musician in the second half of the 20th century, has decisively shaped our notion of artistic avant-garde--in music as well as in literature and the visual arts. John Cage studied architecture, ethnic music and composition, taking free private counterpoint and analysis lessons under Arnold Schonberg. Influenced by Marcel Duchamp and Dada, Cage studied Zen Buddhism with Zen master Daisetsu Suzuki and staged spontaneous activities and happenings in the early fifties. In his later life he became a creator of fine visual art works, predominantly on paper. Vol.I of the John Cage Catalogue Raisonne of Visual art work features his Ryoanji works for the first time published in a book. Referring to the Kyoto Ryoanji Garden and executed in pencil or etching on paper that is evocative of raked sand, they depict the contours of fifteen stones. "
