In 2020, artist Zorica Kelly Markovich was the CFAT x Nocturne Summer Artist-in-Residence in Halifax, Canada, and created a project that responded to echolocation by relying on the sense of hearing and the action of deep listening.

Signal / Return is an immersive sound art piece that uses sound ecology to examine acoustic relationships between living organisms – human and non-human – and their connections with the environment. In this piece, audio recordings of bat communication and echolocation are used to create a multichannel, spatial audio experience.

Zorica invites listeners to close their eyes to connect with the sounds on a deeper level. While engaging with Signal / Return, the artist asks individuals to discern the possibility of interspecies symbiosis within a shared landscape.
