Picture disc 12”, booklet, insert.
Radio recordings from 3 GHz to 30 kHz.
Radioscapes is a disc that invites to discover the electromagnetic landscapes that surround us. The two sides of the vinyl propose to listen and to observe two very different radio contexts: the Paris ring road (side A) and a farm isolated in the French countryside (side B). In each location, the whole radio spectrum was methodically recorded during two weeks and then transcribed into a single audio track. On each side, an image representing the levels of the received frequencies is printed under the groove in synchronization with the sound.
Radioscapes is an exploration of existing artificial and natural signals. As the disk rotates, the frequencies follow one another, as on a radio whose button would slowly rotated: one successively travels across Wi-Fi waves, mobile phones, hydrogen lines observed in astronomy, satellites exchanges, military and aeronautical communications, FM and AM radios, thunderstorm residues …
The disc is accompanied by a silk-screened booklet that brings together a text by astrophysicist Eric Chassefière detailing the physical properties of radio waves and their utility in radio astronomy and the protocol used to carry out the recording of waves.
