Signal Architecture
1224 W Loyola Ave, Chicago IL
July 22, 2025 - July 28, 2025

Reception July 24 at Rush Hour



We rely upon an immaterial and ever-present architecture of signal traffic beyond our senses. Communication networks, power infrastructures, surveillance grids, data centers - all linked through a shared energetic substrate of 60 Hz.

Signal Architecture reveals hidden electromagnetic and seismic languages in the built environment.

Low-frequency (ELF/VLF) electromagnetic waves—particularly those generated by nearby urban infrastructure, like grid-powered devices, converters, and CTA trains—are the raw material of this installation, drawn closer by a copper wire loop antenna.

This electromagnetic (EM) signal will act as the carrier, and will be modulated in real-time by architectural vibration taken by a geophonic microphone on the station’s structure.

Signal Architecture produces a living sonic field transforming container into transceiver.

This installation will be most active as trains at the nearby station come and go.
