Frequency and Volume

Shadows on gallery wall

In his first solo UK exhibition, Mexico-born, Canada-based artist Rafael Lozano-Hemmer’s installation allowed visitors to experience a visual and sonic representation of London’s radio spectrum.

In Frequency and Volume, Lozano-Hemmer transformed The Curve’s 90-metre long arc into an immense interactive environment. Composed of 48 radios which could potentially all be tuned to different channels simultaneously, the installation constantly changed according to the physical position of the visitors.

On entering the space, participants’ shadows were cast on the wall. Monitored by a video tracking system, each shadow tuned in to a radio frequency, changing channels as it moved around the gallery. The outline of a projected shadow affected the tuning, while its size controlled the volume, thus the human body became an antenna able to tune into different frequencies. The resulting sound environment was a continuously evolving composition created by multiple contributors.
