I'm personally not sure it was such a good decision in terms of marketing. I mean, I'm all over it, and frankly, I hope I'm wrong and that they sell out their venues. It was definitely a bold move though. I can in all honesty say that if I were JP, I'd have included a hefty encore of back catalogue songs, just to make sure those who weren't as into the album would come to see me live. I mean, especially if it's something out of the ordinary, like doing A Change of Seasons as the encore again, or Octavarium, or something that they haven't pulled out in a while. But I don't have big bear balls like JP.
Like I said, I don't need an encore, or any of their back catalog this tour, I'll gladly go see it just for The Astonishing, and I hope plenty of other people do too.
