This chapter investigates how do-it-yourself (DIY) cultures in New York City and Berlin make sound and music with “zombie media,” or physical materials rescued from obsolescence that are recycled, repurposed, and reanimated. In situating DIY repurposing practices within a context of conspicuous production, or the tendency to obsess over constant invention and fabrication, it explores zombie media as experimental instrument building, sound art, and multimedia art. Through solo tinkering, group workshops, concerts, and exhibits, participants employ the DIY ethos present in underground and experimental music and art scenes, as well as maker and hacker cultures, to explore the aesthetic, material, and cultural value of electronics at various life stages and afterlives. Some of their tools and techniques of repurposing include: circuit bending, hardware hacking, scavenging electronic waste, and repairing broken audio equipment. Drawing on discussions of the zombie, ranging from its original Haitian context to its widespread use as a symbol for the anxieties of late capitalism and overconsumption, the chapter shows how participants engage infrastructures of waste through an ethic of aversion, cultivating sustainability skills that demonstrate “productive” uses of time and materials, but which nevertheless embody conspicuous production. The lure of zombie media is its reanimating power—a resourcefulness-through-resistance that operates via sincerely held beliefs about labor, frugality, and conserving material goods.
