I have seen Matsuri four times beginning with their time at the Riviera and then the Sahara. I have not yet seen the show at the IP, but I don't doubt that it's just as good as ever.
I dare you to watch this show without smiling and/or laughing. These young performers are excellent, and they give 110% to put on a great show.
I don't think anyone would leave this show not being impressed with what they had seen.
