Thanks Sunshine for the detailed info, i now remember of the things about room acoustic and "population".
For the little history, it happenned to a friend who played his trance tracks live during a party and it sounded very bad : over-present bass, undermixed kick, no highs (it's funny to play live a stereo mix, no ? all the technicity required to press play on a dat recorder then to pretend to play with buttons and stuff is often underestimated by the public

.
Anyway, because he doesn't have any "real" mastered track, he decided to play live on 8 tracks, so he will be able to adjust a few instruments to the room acoustic. (like, bass, kick, snare, charleys (metals in general) ,plus different groups of tracks selected according to their frequency range or importance in the mix). I think that's a good idea for live purposes, especially for dancefloors (house, trance etc...).
Plus it's less boring for the stage performer....
pretty off topic though
