Disappointments aye. It's obvious enough, but we set ourselves up for these things based on how we set our expectations. High expectations tends to result in high disappointment, and so naturally having zero expectations (although not the easiest Pov to have once you've developed your own preconceptions about anything) is more likely to result in being pleasantly surprised. I try not to bring too many expectations into music listening. But I'm still human and have preferences. I think some of my bigger disappointments were related to outside preconceptions that I'd heard about when I was digging backwards into their discog.
I won't go right into the story again but I basically I properly got into the band in 2009 where I started going backwards, rediscovering parts of SC and TOT that I'd heard bits of in the past. I remember finding I&W not very digestible, but I'd heard amazing things about it on the Internet. It was mostly because you don't get the full experience on your first listen, although your impressions of the first listen still determine how it grows on you. I knew there was something great going on here, but until there was familiarity, I just wasn't that into it. So I&W was quite a disappointment to me, considering it was actually one of the last albums I heard from the band (less Pull Me Under, which I had heard quite early).
I was also disappointed at the setlists not rotating this tour. Simply because the 1 time they came to my country, we got an amazing setlist, and then I looked at the Sydney set across the creek and it was a similar yet different set that was just as cool, if not better. And it generated a lot of excitement at the potential of what could be heard. And then following the shows online was a lot of fun. There's probably reasons why it's better the way it is now, but after being spoiled a bit it was disappointing for it to go static.
My biggest disappointment ever though, is that they haven't come back to New Zealand on subsequent tours since Black Clouds.
Anyway, to contrast what I've said. Things that pleasantly surprised me; the performance quality of Luna Park. I see a lot of people that are disappointed with the mix, which is a valid complaint I'm sure (although didn't come to my attention straight away, had it pointed out by the overwhelming consensus). Regardless, the mix wasn't anything special nor an issue for me, I just thought the entire band was on fire. Each member had stunning performances, James was killing, Mike was in the energy. Thought it was the best Live show they've released in their career. I don't know if I still think that but I really enjoyed LALP when it came out.
Was also pleasantly surprised at ADTOE/DT12. I pretty much started following the band just in time to be quite shocked at MPs departure. So I had no idea what to expect with DTs future at the time. So I didn't expect anything. And then ADTOE blew me away. I think someone already mentioned; DT seems to have almost come full circle because, long(er than the average) song arrangements with progressive metal influences, with catchy yet slightly unpredictable structures. That's a basic description I could summarise for WDADU/I&W and it seems their recent output can be comparable to those roots and is strongly representative of these ideas as much as ever, with out adding too many asterisked side notes to this generalised description; which would be required if we were to describe all of their output in a similar way. So I've been very pleasantly surprised at the direction they've taken (in that it feels true and is an honest reflection of what the band wants to do), and I have only excitement about what's to come. But hopefully not excitement with too many preconceptions or I'll set myself for disappoint.
