Well, not always
Modern "music" usually consists of something like a multi-track tape with a track for each instrument. The sound field is completely artificial, created by the mixing engineer panning instruments to wherever he feels like. In that respect, if you can extract individual instruments from a mono recording then you can do the same thing. Would the result in that case be any less stereo than "real" stereo?
The problem is how to extract the individual instruments. I can imagine that say a double bass and a piccolo would be quite easy whereas two trumpets might be a bit more challenging. Anyway, thanks Christopher for the link to your interesting site. One day when I get around to it I'll play with my Bar Trio records and see if I can separate a piano, an accordion and a guitar.
