Just got home, still have unpacking to do, but let me post my quick thoughts.
Performance and setlist wise this was an AWESOME Dream Theater show. However it was a terrible special event, and the sound had major issues. Starting in the first set JP was WAY too loud, and the whole band in general was a bit too loud. Come the 2nd set the choir was BARELY heard at times, and the strings were non-existent. In the end, this was nothing more than a Dream Theater show with some more people to look at. And how they utilized the strings... dreadful. Instead of having them play parts of songs from Lifting Shadows forward, they had them (I believe, again, couldn't hear them) play all/most parts on everything from Illumination Theory on. It would have been especially good if they had switched out Mirror/Lie for Trial of Tears or Breaking All Illusions to make even further use of the strings. There are pros and cons of Mike being out of the band, a con being they likely wouldn't play Space Dye-Vest, but a pro being I am sure he would have made much better use of this opportunity.
That aside, everyone sounded great, with James sounding near the absolute top of his game again. Had this been a local show I would have been more than pleased, but as someone who traveled a good distance for a special event, I'm definitely a little disappointed.
