This chapter converges on the sound-in-film/sound-on-film dichotomy, when Cage revised his aesthetic stance on multimedia sound-system assemblages in the 1960s. Framed around a conference panel in 1967 at the University of Cincinnati, Cinema Now, in which Cage discussed the current state of Underground Cinema in the United States, this chapter outlines Cage’s interaction with the “two Stans,” Stan Brakhage and Stan VanDerBeek, culminating in a detailed critique of Cage’s 1965 immersive interactive multimedia work, Variations V. The chapter begins with a detailed reading of the fundamental tenets of Cage’s negative aesthetic set forth in his seminal publication, Silence (1961), exploring its implications for multimedia and intermedia theories in the 1960s. Two competing poles of interpretation of Cage’s theories surrounding chance and indeterminacy emerged from the first post-Cage generation. The first sought out a reduction of the artwork to its base materials in an act of contraction, whereas the second reached for the opposite, a total expansion of individual medium-specific artworks in a monumental Gesamtkunstwerk, epitomized by Stan VanDerBeek’s theories of expanded cinema and intermedia.
