Electromagnetic hum

I wanted to hear the electricity that makes all this possible - that makes recording sounds and uploading them to aporee and sharing them online etc. etc. into a feasible thing. I took an electric pickup coil and walked underneath the nearest accessible pylon to my home. You can hear in the recording that I am walking under and around the cables of the pylon; the loudest sounds are when I am standing directly beneath the wires. It's amazing to think of how this sound imbricates all our gadgets and the landscape.
