This book is the first study of John Zorn’s ‘file card’ works, with special focus made on the pieces Godard (1985), Spillane (1986), Interzone (2010), and Liber Novus (2010). It explains the unique creative process behind these compositions, contextualizing them in relation to the history of file cards, the ‘open work’ concept, cinematic listening, and uncreative aesthetics. Semiotic, hermeneutic, and ekphrastic analyses draw hypertextual links between the four file card compositions and the worlds of their respective dedicatees: author Mickey Spillane, filmmaker Jean-Luc Godard, novelist William S. Burroughs and painter Brion Gysin, and psychiatrist C. G. Jung. This book will appeal not only to those interested in Zorn’s music, but also to scholars of music semiotics and hermeneutics, intermedia studies, and avant-garde music.
