Really would like to see The Glass Prison. From WDaDU, either A Fortune in Lies or The Killing Hand. I still haven't seen Metropolis live myself, but there are enough live versions out there I don't feel I have to see it. ACOS would be great, but I don't see them killing 25 minutes unless it's a current release. Stream of Consciousness is the only other one I really would love to see. Other than that, I've seen every tour since 8vm, so I'm covered on all the songs from the last four albums.
