hey jeff welcome to the board!
just to manage your expectations I wouldn't count on nightblindness..........to my knowledge he hasn't played that since he started touring for dtl 18 months ago............nemesis has really replaced nightblindness for now in its role on the set list......I was actually thinking the same the other day and the extended outro to nightblindness is absolutely amazing live!
but as this is the finale for dtl I just really doubt we get it.....it most definitely has not been played on this ray co-headliner tour
enjoy the show!
