ah! YUI is another one i'd love to see. I almost saw Dir en Grey, but got snowed into my house and couldnt see them, along with HIGH and MIGHTY COLOR, they were at Anime Central in 2008, and one of my guy friends asked "Hey, do you want my ticket?" and i declined. I'm kicking myself now.
Also, Miyavi is going to be performing in Chicago by me tomorrow night but I'm not going...i like his old stuff
