An expansive LED display, flanked by speakers, spans the space. Electromagnetic wave data, imperceptible to humans, used by mobile phones, Wi-Fi, terrestrial digital, and FM radio, is collected by antennas installed outside the museum and converted into image and sound in real-time through the LED display and speakers. Together, they make visible and audible the invisible streams of electromagnetic waves flying around at all times.
This work manifests as an 'ecosystem,' the artificial flow of electromagnetic waves that, although we are normally unaware of them, form an essential infrastructure for today’s urban activities. It was originally presented at the Sapporo International Art Festival 2014: City and Nature, for which Sakamoto served as Guest Director. On that occasion, it employed a large-scale video display and speakers installed in the Glass Pyramid at Moerenuma Park in the Sapporo suburbs. For the exhibition Ryuichi Sakamoto | seeing sound, hearing time (Japan, 2024–2025) at Museum of Contemporary Art Tokyo, the large video display has been replaced with an upgraded version of the elongated LED display first used in an outdoor installation in Beijing in 2021. By means of the oscilloscope-like installation, the invisible infrastructure of the ever-transforming Tokyo megalopolis is depicted in images and sounds.
