Saturday: They should've called it the "Dreaming" vs. "Dream Police" Tour. Probably the two fluffy-haired '70s bands you can feel least guilty about having on your iPod, these influential pop-rockers aren't exactly reinforcing their cool, ageless sides by playing casinos this summer. But it's still cooler than seeing them at a rib fest. Cheap Trick should know how to work the room, as the Illinois foursome -- all-original, except that Rick Nielsen's son has been filling in for the injured Bun E. Carlos on drums -- is staging "Sgt. Pepper Live" at the Paris hotel/casino in Las Vegas on weeknights. Deborah Harry and her fellow Rock and Roll Hall of Fame bandmates Clem Burke and Chris Stein haven't been touring as much as the Trick, so their appearance might be more of a special treat. The bands are swapping headlining duties from night to night, but they each play a 75-minute set regardless. (8 p.m. Sat. $55-$65.
