I just bought Fortress a few days ago, and I can honestly say I've NEVER been so blown away by an album on first listen. There wasn't a single second that didn't amaze me. I love it because it's so chaotic and unpredictable (even when compared to other prog), but at the same time it's cohesive, and I immediately fell in love with the vocals. They're backed by so much attitude and confidence, whether clean or screamed/growled. Incredibly album, I'd have to say Bloodmeat is my favorite track right now. I may or may not check out Kezia but I don't feel like I need to...
