Actually, I'd say they do have some very specific old-school elements. It's metal that is rooted much more in an influence of Iron Maiden, Dream Theatre, Rush, and a bunch of other stuff more than than anything recent.
I have listened to the album quite a few times now and am really into it. It's just plain great. I also hear a vague draw off of stuff like A Perfect Circle and a few more modern metalized (if not pure metal) bands.
Anyway, the best thing I can say about it at this point is that Operation Mindcrime II is out (or coming out - I forget the date) and I suggest anyone looking into that either get this instead, or at least also. It's all too easy to get caught up in some bands pedigree, despite the fact that they are putting out sub-par records right now. This album is intense, musical, accessible, artful, and above all else, metal. I hope people buy it. Especially some of those in this forum. I think a lot of people will be surprised if they don't know them.
I know I was. Thanks a ton for the suggestion. Like you, I already know this will be in my year end top ten. It really is that good.
I'd be interested in hearing what order you suggest getting their other albums in......
