The presence of a keyboard solo annoys the piss out of me. Especially considering it's Dream Theater and thus the keyboard solo is probably like 3-7 minutes long. They have a lot of great standard length songs they could throw in in place of it, and I'm sure the audience would rather have that.
I'm still figuring they've got Solitary Shell, Caught in a Web, As I Am, and a few other tricks up their sleeves yet. Another 2-3 shows and all the songs should be out.
