Well no never have played in a three piece band,am not competent enough to do more than hack at guitar and shout . but heard plenty who pick their instruments well and then play them in away to maintain the balance.
But I was really making the point that some of us are a little loose about what is OK re tapes ,gizmo's and P.A.
If you want to ban pre recorded music, ban the P.A they are mostly played through.
If an acoustic instrument cant produce the same effects as an electric one the get an electric one,but don't pretend its an acoustic performance.
If the audience soaks up too much sound then have a smaller audience and more gigs.
I just wanted to say why pick on the unfortunate person(s) who didn't have their own band when you allow all the other stuff that is also not strictly acoustic.
Personally I would probably have enjoyed listening to all the above mentioned artistes doing what they do best entertaining.
As long as it wasn't too loud!!!!
