"Shattered Fortress" is the final chapter of Mike Portnoy's AA Twelve Step Suite. It has all the main riffs from the past chapters to kinda sum up everything. So no, you're not crazy.

Here's a link explaining the idea of the AA series:

It just seems to me that he uses a lot of the same fills over and over. I know most of everyone here are guitarists, so maybe you don't know what I'm talking about (I know I don't even know what I'm talking about half the time!).
To sum up their new album.... it's great! Once again JM's bass is buried in the mix which really disappoints me, but all in all, a pretty solid album. I really love the first track though. That intro is Heavy! w/
