I honestly wasn't too jazzed about TGE. TSOAD is leaps and bounds better, though. Right now I can't honestly say that it has grabbed me more than The Whirlwind, which I thought was a phenomenal morse offering. I'd say it IS one of the best albums of their careers, and certainly the best of this particular line-up, but just a TOUCH oversold; and that's not bad, because I expected it to be massively, massively overhyped by Portnoy. I actually don't blame him for the way that he hyped it, as it is a phenomenal album. In some ways, it suffered, to me, a few of the same pitfalls that Astonishing (if we're going to make comparisons) experienced.
I do like disc 2 more than 1. The Battle was a huge piece of work and had me enthralled. So yeah, if you haven't went out and listened to this - you need to get on it. I think this will grow on me, and I wish that Portnoy would focus as much as possible on this particular band, because there's a lot of magic between these 5.
Edit: Also I'd just like to say that, in the way that Astonishing had LaBrie do those peculiar fast rap vocals for The Path That Divides (??) I really liked how the band did back and forth vocals on Confrontation. Bill/Eric really did add in a lot of color to the collective palette.
