Unhappy Circuit is an electronic musician and new media artist who expresses a holistic, interdisciplinary thematic consciousness through works that fuse science, art, and technology. With works that integrate various media, technologies, art genres, and multidisciplinary perspectives, Unhappy Circuit has continuously expanded the understanding of the universe and humanity by connecting the universe, nature, the unknown, and humans. A Synthetic Song Beyond the Sea is a work that synthesizes the vocalizations of blue whales and human music by using AI to create a tune that both whales and humans can hear and interact with. It suggests the basic attitude required for humans to coexist harmoniously with nature, and by extension, with other humans, and a future model for such coexistence.
