What is it with Cirque du Soleil and Vegas? Ever since Steve Wynn invited Mystere to set up shop at Treasure Island in 1993, the French-Canadian circus brand that has made absurdity its trademark has become an inextricable part of Vegas entertainment. As of this writing, there are 5 Cirque du Soleil shows that call Vegas home (6, if you count the Cirque-owned, but not Cirque-developed, Blue Man Group) and there have been a total of 11 Cirque shows that have had permanent runs in Las Vegas. Some of them had shorter runs than others...   Come aboard, we're expecting you... Kà was the fourth Cirque du Soleil show developed for the Las Vegas market, and it has the distinction of being the first Cirque show to tell a cohesive narrative. If you’ve never seen a Cirque du Soleil show: most Cirque shows have a theme but not a narrative. Mad Apple is themed after New York City.  “O” is themed after water. I’ve read that Mystere is themed after “the origins of human life and our connection with the universe,” so you know, someone smoked a lot of weed.The story is fairly simple, but I do think people need to know the basics of it before they see the show. Compared to the current iteration of Awakening (which now practically serves up the entire story to the audience on a silver platter) Kà’s narrative works best if you know the story notes going in. A twin brother and sister are part of a tribe that gets attacked by bad guys. The twins are separated and most find their way back together and also save their people.  Each twin kind of goes through their own rite of passage on their journey before they are reunited and save their people. The massive sandcliff deck. Let’s talk about the tech behind Kà. Kà is an absolute technological marvel. It doesn’t have a proper stage floor, it just has an open pit that is full of various nets and airbags for the performers. Instead, there are two moving stages that are so massive and heavy that Cirque had to go outside of the theater industry and turned to Timberland Equipment, a company that normally builds mining equipment, to build their moving support structures. In one scene, one of the moving platforms is covered with 350 cubic feet of “granular cork” imported from Portugal to simulate sand on a beach. At one point in the show, the larger sandcliff deck has these pegs that stick out of it. As they are supposed to look like arrows shot onto the surface, they pop out of the deck very fast. But the performers have to climb using these pegs, so there are dual safety features incorporated into the pegs. First, they won’t shoot out if anything is blocking them, and second, they won’t go back in if there’s any kind of weight on them.  I could go on and on. Kà has won awards for its technical achievements in theater. I even read somewhere that it was the most expensive theatrical production ever made, but I couldn’t corroborate that anywhere. This machine makes french fries 3 different ways! Of course, all the technology in the world doesn’t necessarily give you an entertaining experience (Take notes, Avatar: The Way of Water). I’m happy to report that Kà is indeed an extremely entertaining experience, and one of the Cirque shows that I have enjoyed the most. I’m always looking for a narrative, so the fact that this show has one helps that enjoyment immensely. That being said, I recommend buying a program or at least reading through the show’s wikipedia page so that you can get a basic understanding of the story beats and recognize what’s happening.Like any well-told story, the show does a good job of varying the pace. There are intense action sequences and there are peaceful pas de deux. You have, of course, your typical array of Cirque acrobatics, some of which even takes place in the wings on either side of the stage. I recommend you arrive for your seats about 20 minutes early, as there is some pre-show action to enjoy. I really enjoyed the final
