It feels almost embarrassing to chime in on the rotating setlist thing, but rather than saying I'm for or against (can you already tell I'm for?
) since I've been on the arguable two sides of the experience, maybe I can bring something to the table: in 2008 I got a bunch of favorites in São Paulo that the folks in other Brazilian cities (I think Rio the day prior and Belo Horizonte or Brasília the next day) didn't get, and in 2010 I got a setlist that was less geared towards my personal favorites than the Rio setlist the previous/next day.
I do have a general perception that the concert with more songs that I hold dear to my heart was better than the other one... but that didn't make the 2010 gig a lesser DT gig. I missed out on Solitary Shell, Mirror/Lie and In the Name of God, but in São Paulo we got the extended Hollow Years and a big chunk of Act II of SFAM (Dance of Eternity, One Last Time and Spirit Carries On), along with the Pull Me-Tropolis medley (which I dig). Both shows were just as Dream Theater-y (the major advantage of 2008 was that it was a longer show), both shows had big tour-specific touchstones (start with ANTR, end with TCOT), they definitely delivered on the promise of playing a Dream Theater concert. That's what I feel MP aims for on ALL setlists he pens – and really, what the band angled for even with the static approach. Changing or keeping it simple, it's always those five guys on stage (and the crew) making magic happen.
Like TAC, I'm also not one to travel for other DT gigs. I know people who do, and more power to them, but that's just not in the cards for me. So I take what I get, and like TAC, to me it feels like a plus to keep tabs on what they're playing, watching/listening to bootleg recordings of shows with different setlists... It's like a little treat even if you're not there.
crystalstars17, I wouldn't want you to change your opinion on the matter just because it's different than mine, but what I hope is that the band can show us all that whatever the setlist approach, they're a force to be reckoned with onstage. I think the craziest exploits like playing a full album by another band are behind them at this point (unless, like Scotty said, it's something announced in advance), so the perspectives seem positive (still rooting for JLB to shift gears and get back on track pitch-wise, but that's another issue entirely).
