In the digital age's relentless march forward, a once-ubiquitous object faces obsolescence. Directed by Rico Wong Lok Yiu, this contemplative documentary, "Compact Disc," explores the life cycle of the optical disc, from its revolutionary birth to its quiet descent into nostalgia. The film is not merely about polycarbonate and aluminum, but about the profound cultural shift it represents, examining the technology through the eyes of collectors, musicians, and the last guardians of a fading physical format. As streaming services dominate, the documentary captures a poignant race against time to preserve both the medium and the memories etched into its reflective surface. With a tone that is both elegiac and deeply curious, it paints an intimate portrait of an artifact whose quiet click and whir once scored a generation, inviting viewers to reflect on what we gain and what we leave behind in the name of progress.
