While a narrative of technologically driven advancement dominates the digital age, an accompanying cultural subcurrent of “newtro”—of throwbacks, remembrance, and nostalgic repurposing of bygone materials—marks neoliberal time in contemporary South Korea. This course engages with the OSTs (Original Soundtracks) of two K-dramas—Reply 1988 (tvN, 2015) and Reply 1997 (tvN, 2012). We critically examine their featured love songs’ entanglements with modern Korean temporality. In what ways do vocal, instrumental, and environmental timbres invoke nostalgia and historical memory? What global infrastructures form the conditions of possibility for the production and circulation of Korean love songs? How do love songs generate and orient desire? Can nostalgic gestures engender alternative relationships between present, past, and future? And if so, what possibilities and pitfalls emerge? The first and second halves of the course are each centered around a significant juncture in late twentieth-century South Korean history: 1988 and 1997. Reading across fields such as Korean studies, music studies, religious studies, and anthropology, this interdisciplinary graduate seminar interrogates how nostalgic sonic imaginations formulated in K-Dramas might prompt a reconfiguration of modern temporality itself. Juniors and seniors in the college are welcome.
