Friend of mine went to a recent KISS concert. Said he liked the show but it was the exact same one he saw ten years ago.
When I see commercials for rock and roll cruises, most are around a year ahead of time. My first question when they announce the music line up is will any of those musicians still be alive by then?
KISS will become a franchise act. When Gene and Paul are too old to hit the road, they'll hire stand-ins like they've done for Ace and Peter. The face makeup and costume designs have been copyrighted. Don't be surprised if there's two or thee KISS franchises touring at the same time.
Gene Simmons knows how to make money.
It probably WAS the same show - it's unlikely their instruments were plugged in. I used to work with a musician and he told me a LOT of bands prerecord and lip sync.
