I hope no one minds, but I have two different versions. This is because they would probably be promoting a new album, so the first version includes some new music. There are some exceptions, but for the most part I tried to stay away from things they did on the last couple of tours. Also, in both cases I tried to pit together a set that reflects the band's entire catalogue.
Version 1.0>
SET ONE:
1) New Song (fastest, heaviest song from the new album, probably the first track, 6-7 min.)
2) The Ones Who Help to Set the Sun
3) The Silent Man (Live Scenes or "electric" version)
4) Another New Song (something a lot more "proggy" this time, about 8-9 min.)
5) Just Let Me Breathe
6) Piano/Keyboard Solo / One Last Time (7-8 min. total)
7) Ballad, or slower or "mellower" song from the new album
8) Along for the Ride
9) About to Crash
10) Instrumental Track from the New Album, expanded to include solos by Myung and Petrucci (12-15 min.)
11) Metropolis
I got this crazy idea: instead of having a regular intermission, why not have a comedian take the stage and perform for about 20-30 min.!
SET TWO:
1) Another New Song (9-10m min.)
2) Enigma Machine / Drum Solo (A holdover from the last tour, I know!)
3) As I Am
4) Forsaken
5) A Rite of Passage
6) Lost Not Forgotten
7) The Enemy Inside
8) Longest or "Epic" Song from the New Album (18-22 min.)
ENCORE:
1) To Live Forever
2) Pull Me Under
3) The Root of All Evil
Version 2.0>
So...if they don't have a new album to promote, but wanted to commemorate a certain couple of anniversaries, it might go something like this:
SET ONE:
1) Surrender to Reason
2) The One Who Help to Set the Sun
3) The Silent Man (Same Version)
4) A Change of Seasons (Not where most people would put it, I know, but I like to stay chronological for the most part.)
5) Just Let Me Breathe
6) Piano/Keyboard Solo / One Last Time
7) About to Crash
8) As I am
9) Metropolis
SET TWO:
1) Outcry
2) Enigma Machine / Drum Solo
3) Octavarium
4) Forsaken
5) A Rite of Passage
6) Lost Not Forgotten
7) Behind the Veil
SAME ENCORE: Live / Pull / Root
