From tnt-audio.com - We Support Real Stereo:
"It [stereo] was a method for capturing the spatial information inherent in live performance, including the sound and positioning of instruments and voices and a sense of the acoustic in which the performance was taking place.
When reproduced by two appropriately sited loudspeakers, a facsimile of the original performance, including this spatial information, could be produced. Like many brilliant concepts, stereo sound recording and reproduction was elegant in its simplicity."
Stereo. Good stuff!
