I'm not as irked as some of you about the current tour (though admittedly, I sorta lucked out with some pretty good shows), but there were some questionable decisions, especially toward the end when Unnatural Selection and New Born began being rotated out for whatever reason, and it's not like they were replaced with another song. They were just dropped altogether, resulting in shorter sets. Likewise, while I think we can still depend on seeing New Born appear during the next tour, but less frequently. Some have suggested swapping it with Unnatural Selection at every other show, which doesn't seem like a terrible idea, though quite frankly, I'd still prefer to hear both. And yes, Matt needs to return to the doggone piano during New Born.
Speaking of piano, I'd really like to see its sequence extended. This may be easier if they remove the towers (and I think they will), as it can be wheeled in and out more efficiently without them, and the piano songs can be divided up throughout the show if what Matt says about audience contact is actually true.
As for the older songs needing to be played more, I think it goes without saying. Expending the setlist length can only do favors, especially as Muse's library grows and they have more and more hits to plow through at future shows, endangering rarities even further. I mean, yeah, while it's fun to brag that I got the only instance of Bliss in the U.S. all tour, it's fairly depressing at the same time.
I suppose I'm not as picky as some about this current (soon-to-be-ending) tour as some seeing as how it was my first tour seeing Muse live. In fact, my biggest regret may be not being able to see MK Ultra at any of my shows, since that song seems doomed next tour if the fact that it's on The Resistance and rarely ever played is any indication. But because of that, I've missed out on seeing some great songs from the first four albums, and I think all of us would love a chance to see those revivals.
