On the one hand, using a traditional narrative approach, this dissertation examines disco's historical trajectory from an underground movement to a mainstream phenomenon, and analyzes its relationships to American cultural and racial tensions during the 1970s and 1980s. On the other hand, this dissertation also departs from traditional historical approaches by emphasizing an archive of personal experiences, memories, and reflections produced over the last four decades by individuals, living and dead, whose creative expressions help give disco its definition. Each chapter is organized around the story of an individual DJ whose work and play reflected the broader disco landscape. Together, the anecdotal experiences of these DJs help to conjure a collective biography of disco, emphasizing the significance of disco not only as a "genre" of pop music, but as a larger reference point for shared, and sometimes contested, cultural experiences.
