Drums sound alright, a lot better than DT12, but still not as good as most of MP's stuff.
As I said before, it has a pretty retro vibe. Someone mentioned I&W, and that's a feeling I get as well.
LaBrie sounds good, although those pitch correction moments some have already pointed out are pretty embarrassing.
NOMACs being AIs gives some more credit to my theory that they end up a third party, one that both the rebels and the empire will need to join forces to defeat.
Overall I'd say the track is fine, but nothing really special.
they're bound to play something else, isn't it? or it is really just the album and that's it?
I'd say a pretty definate no. They want to treat this like a show. Image you watching a play, and then after the play is done, the actors play one more scene from a different play. That would be a really weird thing to do.
