Found this on a posting in RS.COM in response to questions about B stage:

"Call the venue and ask.
The Columbus show does not specifically show one but has a floor grid with space. I called the arena and they said they could "confirm" a small second stage between sections 104 and 114 of the lower bowl and between sections 3 and 4 on the floor."

Now sec 104 and 114 face each other across the arena in the non floor seats. This would imply something like a ramp arcing around the back of the arena in the elevated seats. My guess, if the report is correct, is that it is a new way for MJ to work the crowd (like the side ramps in '81). I doubt the whole band gets there. So can any one confirm, deny, or better explain this report?

Yes, i imagine something like a trident with 3 aisles.
2 catwalks like in Hampton 1981 and one in the centre but no real B stage with a drum kick.
It would "explain" some prices far from the stage.

You mean something like the catwalks U2 had one there last tour?

or maybe they'll have a small 'c' stage for Mick & Keef to do some acoustic stuff and then the traditional b stage too

?

hope so

catwalks do nothing for me
