2 - The opening act, Kate Miller-Heidke. She's from Australia and also opened for Ben Folds when I saw him solo at UPAC in Kingston, NY, two years to the day before Tuesday night's show. It really says something about the songs when I only heard them once two years ago and I recognized them again. Specifically, her song "Caught In The Crowd" is very powerful, and upon further investigation I was surprised, but not shocked, to learn that it won the top prize in the 2008 International Songwriting Competition. It's that good.
3 - Ben Folds Five, dude! I mean seriously! I waited 10 years for this show! Sure, I've seen Ben Folds solo twice - in 2002 and 2010 - but this is the original.
4 - The setlist. Again, my reference is a Bruce Springsteen concert, where they keep things moving one song to another. On Tuesday night, with the exception of the last 3 or 4 songs of the set, the band had at least a little bit of a pause between every song. Also, most of the show wasn't even attempting to keep the momentum and energy moving forward quickly. Most of the set was structured: upbeat song, downbeat song, upbeat song, downbeat song, etc., until the last few songs that were all upbeat. And I don't mean this as a criticism - it's just different, and it allowed the show to just kinda wash over the crowd as a whole.
5 - My lack of expectations. Of course I expected the show to be good, but what I was not expecting was a certain song. We talked about what songs we might hear before the show, but I didn't go in with a hard list of songs that I was hoping to hear. I've seen Springsteen so many times at this point that I do go in with a mental list - songs I have been waiting to hear live that I haven't yet. But going along with the above point about the setlist, I just soaked this show in instead of waiting for a particular song.
All in all, a great show from beginning to end.
