That's pretty funny.
You're the one who went all broad-stroke here. I only related an anecdote that one guy told me. How in his band, they weren't allowed to have any on-stage amps, and everything had to go through the PA and be controlled by the sound guy. Where did I ever say or suggest that anyone who
"pre-plans their on stage sound is akin to musical sinners"....???
Gigs are always planned out. It's not supposed to be an "improvisational jam session"..but planning out your gig options is not the same as not being allowed to use any amps on stage.
There are different degrees of "planning" and "control". If you want to look at a Broadway show....that shit is planned out down to the micro-detail if at all possible. There's way too many "moving parts" for it not to be.
However, for a basic band concert, it's NOT required. If you haven't noticed, that's why so many bands DON'T sound exactly like their recordings, which in this day and age of digital and MIDI, is easily attainable.
Sure, some bands take the Broadway route, and have every micro-detail controlled by someone or something....but again, all I'm saying it that it's lame and not required for a typical rock band to do.
You seem to imply that it's inevitable and must be micro-managed, otherwise they can't have any kind of conistancy....????
Well, in that case, they are not that good if they need that much programming to sound good....and as Lt. Bob said....it's also about the style of music. Some styles may need more programming, but it's not an absolute. I think you're confusing "practice" with "programming".

I watched some of the the "Marley" documentary last night...and I can tell you for sure, there was little "programming" and "micro-managing" of the whole show. They were just good musicians who could play well together.
If you get "Palladia" music TV.....all New Year's Day they will be showing the Guitar Crossroads concerts back-to-back from over the years. Check it out, see if you can spot the "programming".
