I agree with people on here. I do love LPs old sound but I don't want them to bring it back. I feel they are done with it. But really, if they went heavier, or more on the rock side, I don't see that as going back to their old sound. Songs like When They Come For Me, Given Up, No More Sorrow, Wretches and Kings I cannot see would fit on HT or Meteora. Think people would disagree but I saw it as a progression and being creative.
Anyway yeah maybe take this with a grain of salt as it may be far from the truth.
