Dr. Jeffrey Thompson – Sphere of Io (Jupiter’s Moon) – NASA Space Sounds

‘The sounds used on this CD are recordings taken directly from the NASA Voyager I & II Space Probes as they passed near different planetary and moon bodies within our solar system. … Each “instrument” you hear on this CD is actually the recording of a Voyager planet recording compressed electronically down to its fundamental harmonic frequency. At this range, the space recordings sound like unique musical instruments.’
