Unamplified concerts I would suggest are multi-dimensional, essentially you have the sound of each seperate instrument mixing with all the other instruments. All this sound arrives at the listener with varrying intensities and timings. I don't hear anything close to stereo or mono at these concerts, this is 'real' sound. I hear only a poor facsimilie of this sort of soundstaging with stereo.
As for mono vs. stereo recordings. I generally prefer stereo except in earlier stereo mixing when sounds were often hard panned to either side. Therefore, a voice may come directly out of the left side speaker, drums out of right, ugh! Listen to late 60's, early 70's rock recordings, way too many do this crap, I prefer the mono releases on these, much more natural sounding.
