Songs of Emerging Endangerment by artist TJ Shin, commissioned by Clockshop, is a sound installation using mimicry to map systems of global migration. Installed at Los Angeles State Historic Park in a city shaped by Cold War–era urban planning and waves of migration from the Asia-Pacific, the project features a 30-foot-tall sculptural air raid siren that projects a composition of imitated bird calls scheduled throughout the day. In an open call process, 50 participants connected to regions along the East Asian–Australasian Flyway were asked to imitate the calls of endangered bird species that travel the world’s largest bird migratory path. Participants in the first round imitated the field recordings of 15 species, selected based on their image, geographic range, and habitat. In the following rounds, participants mimicked the voices from the previous ones, creating a structure of repetition and response. This process of interpretation between people, birds, and their environment amplifies and reorganizes how information, bodies, and architectures circulate through landscapes shaped by US militarization. Birdhouse air raid sirens, nicknamed after their appearance and once used as instruments of civic defense until 1985, can still be found throughout the Los Angeles landscape. Set to sound hourly from dawn to dusk, the reproduced two-channel siren serves as a timekeeper, punctuating the surrounding park and city’s rhythms. Projecting compositions of sonic feedback to hear the calls distinctly in proximity and faintly in distance, the work examines how mimicry—and the differences it produces in process and perception—both extend and transform instruments of the Cold War and their fields of power. The resulting sounds become signals, emphasizing how communication between people and surveillance technologies informs our relationships with natural, social, and built environments. At once a sonic rehearsal and social strategy, Songs of Emerging Endangerment invites reflection on the ways our urban spaces are shaped, and how our relationships to them might be reimagined.
