I just had a vision about JP playing that opening melody to ACoS and a crowd going fucking insane, with me in the center of it.
So if this epic IS ACoS, I really hope I can see it live. It would just be a monumental moment in my concert-going life. Actually, the same goes true for Octavarium and Learning to Live, but I bet ACoS would get the biggest response from the fans at large since it hasn't been played live in any part since the 2003/04 tour.
