It's cool to have glimpse of what is technically going on on stage.

What I loved was this :"Not only does Journey's sound drive the graphics, but the audience reaction can trigger the images that illuminate the entire crowd."
I do remember watching that big screen and loving the way the music matched the visual show.
LOL,if the audience had a role in that,then I might be responsible for 2 images of the GGBridge during "Lights"..
