Brood FM attracts and broadcasts the signals of human and non-human actors throughout the city via the creation of contextual micro-environments on Roosevelt Island. Through a combination of standardized construction scaffolding and mesh, modular building logic, native plants and animals, and recording and transmitting devices, these environments will enchant the native species by modulating surfaces and patterns, creating a variety of conditions with interspecies resonance. A brood speaks to an arrival of life, a rhythmic materialization produced by a collective presence. Brood FM anticipates the emergence of the island’s urban ecology, acting as an ambient antenna for the city.
