Heyo, these are all just ideas. You can always say "I don't want to do that", and that is totally okay.
If you're looking for well produced recordings of live music, the "Hall & Oates: Live at the Troubadour" concert in bluray is very excellently recorded and produced. It does use the center channel to add some fill to the concert sound, but it does it very well and it's seamless. It also uses the surround channels to add "audience ambience" the experience.
