Screenprint from one of the first sound multiples ever created. Published by Edition Block in two versions: the complete sound installation in wooden box (edition of 35-36 copies) and this screenprint in red (70.2 x 70.2 cm, edition of 35, signed and numbered). Created for the 200th anniversary of Wolfgang Amadeus Mozart's death, Mozart Mix reflects Cage's fundamental aesthetic principles of chance, indeterminacy, and the dissolution of boundaries between composer, performer, and audience. The screenprint features a mesostic poem—a vertical reading of letters spelling MOZART—with the text "Music without horizon soundscape that never stops." The reduced lyrical form evokes Japanese haiku poetry, while the visual arrangement embodies Cage's literary experiments. The complete Mozart Mix installation contains 25 cassettes with different recordings of Mozart compositions and 5 cassette players in a wooden box. Each tape is a different length, prepared as an endless loop. The public activates the sound installation by selecting and playing cassettes simultaneously, becoming interpreters of Cage's composition. Random musical passages from various Mozart pieces meet in unpredictable constellations that will never repeat. The edition of 35 corresponds to Mozart's lifespan of 35 years. The playful character of the work references Mozart's own 18th-century musical dice game, "Anleitung zum Componieren von Walzern vermittels zweier Würfel." This screenprint—independent of the sound installation—stands as a visual manifesto of Cage's philosophy. Created one year before his death, it represents a summation of decades exploring chance operations, Eastern philosophy, and the nature of musical experience. For collectors of twentieth-century conceptual art, sound art documentation, and those who recognize Cage as a revolutionary figure across all creative disciplines, this is an essential work.
