Lost and Found Sound: Listening to the Northern Lights

We experience the sounds of the Aurora Borealis through the ears of sound recorder Steve McGreevy. Very low radio frequencies accompany the Northern Lights and at the equinoxes, when the signals are strongest, McGreevy heads north to listen. He hears the chirps, pops and choruses that play out when the Earth's Magnetic Field interacts with the Sun.
