We allowed acts to run to 115dB at the FOH, 125 feet out from the stage. Any idiot who couldn't live within that restriction not only belonged in jail, he belonged in an insane asylum. I also cruised the area covered by the remote far field stacks, where the FOH engineers couldn't hear them. More often than not I had to tell them to turn those up. And one of the worst sounding shows ever was 'Boston'. Tom is a nut about vocals being on top, so he won't let his FOH guy go higher than 100dB lest the vocals get buried, in his estimation anyway. I couldn't get him to turn it up to a nice comfortable 105dB.
I just checked my RTA files, when Matthews played for us they ran 105-110dB. If Tampa has a problem it's because they won't spend the $ to sufficiently isolate themselves from the neighbors. It can be done.
I saw Boston at the Alamodome in San Antonio, had to be about 15 years ago. Don't remember it being that out of balance. Actually was one of the better sounding arena shows I'd been to. Our seats were close enough in to see pretty well but pretty far off sideways to the stage. Maybe in a different spot, it was more that way, don't know.
Saw Page and Plant at the same place, horrible sound, couldn't tell what was going on half the time. Not due to volume but just a horrible mix. One of the worst I'd been to.
