Last week I wrote about how the Rio is turning the volume way up on sexy. But here is an excellent example of how relative that can be in Las Vegas. After all, the Rio opened with what then were considered very sexy cocktail server outfits only to make them sexier less than a year ago.

Here is a photo of Rio's "Show in the Sky," taken back in February, before the new, sexier show was installed. As you can see, it features attractive people throwing Mardi Gras beads down to folks on the casino floor.

Not exactly hard on the eyes. But in the photo taken yesterday, bottom, you can view the look of the revised show: The attractive people now make dance floor moves grinding on each other while tossing beads to the folks on the casino floor.
