I really wish I hadn't missed them (twice) while they were supporting Lateralus. I really had some high hopes set on hearing "The Grudge". And no "Sober"? Not that it wasn't an awesome show, but for my first time seeing them, it could have been better.
I have to say, though, that I've been listening to 10,000 Days a lot over the past week or two. I picked it up when it first came out, listened to it a few times, then pretty much set it aside because it struck me as not being nearly as good as Lateralus (or Undertow and Aenima, for that matter). Now that I've really been giving it a chance, it's grown on me quite a bit. And seeing a nice chunk of it live definitely helped.
