Artists performing concerts in similiar style to Ayu?

Yeah, the only person I can think of who has such extravagant concerts like Ayu is Kumi Koda. I mean, some of the things she does aren't as big, but there are only a few exceptions. She relies heavily on dancing (more-so her than the actual dancers, sometimes, lol), has a huge stage and audience, lots of props, over-the-top costumes, and really story-driven (and kinda unnecessary, lol) intro videos. Personally, I like Kumi's concerts even better than Ayu's. She's either blowing me away with her vocals, or making me laugh with a ridiculous outfit, or I go aawwww~ because she brings a fan onstage, or whatever.
