Yeah, it seemed like a mash-up, and that appears to be exactly what Ayu was going for. Unless for some reason I'm reading too much into it, but it seems to fit together too well to be simply coincidence.
After watching the concert a few times, the entire setlist seems to have been created with
past concepts working together in mind, to bring the performances into the future. Or something like that.
01. I am...-intro and performance from AT02, taiko drummers from CDL05-06
02. Moments - performance was from AT05, camera trick and fan dance from AT05
-inst- - tissue dance introduced in CDL07-08 was inserted here
03. STEP you - performance from CDL07-08 + Ladies Night transition, mixed with "cute" elements from CDL08-09 and possibly the clowns from A MUSEUM
04. EnergizE - performance from AT09, mixed with "cute" elements from CDL08-09 and possibly the clowns from A MUSEUM
-inst- - jam session by Yocchan... any tour's could apply... AT06's? The ones at a-nation?
05. About You - performance kind of from AT05 without dancers, solo and was standalone
-inst- - Midomaro/Maroring ballad dance from AT09
06. momentum - performed a bit like the beginning of the AT09 ballad section, had something like rainy day's finale at AT06 with a couple being lifted into the air by the end of the song
07. You were... - performed a bit like CAROLS from AT05 on the rotating stage
-inst- - Shu-ya solo dances from a-nation and the like mixed with more elaborate version of ring performance from AT07ish
08. Pride - Shu-ya solo dance mixed with AT06-ish performance and gospel choir from CDL05-06 (and others) and rainy day AT06 finale is kind of touched upon again with a couple being hoisted up
09. INSPIRE - intro music, performance and style from AT05, walked around arena/stages however
10. Because of You - performance/vibe from AT03-04, new microphone/sword prop instead of the stand, performed on middle rotating stage instead of main stage
11. 1 LOVE - performance from AT07, not much was changed
12. until that Day... - performance from AT07, not much was changed
(countdown) - no Ayu speaking in English this time around...
13. Humming 7/4 - the usual
14. evolution - the usual
15. Startin' - performance from CDL05-06/AT06, placed at the end of main act
(encore)
16. teddy bear - performance from AT03-04, sitting on arm of the chair though
17. Sunrise ~LOVE is ALL~ - performance kind of from AT09, but more like a-nation '09 than anything
18. Boys & Girls - the usual
19. RED LINE ~for TA~ - brand new dance, replacing MY ALL
I wonder if it's just me, haha. But it appears that basically the entire show was crafted using past materials, much like BoCDL06-07, but with more creative changes in outfits and such. Quite a bit was taken from AT05 which makes me wonder if she'll try to break away from it in the coming AT10. It is a bit nice that the CDLs are becoming less and less like shows that she throws together and actually sort of feel like her tours nowadays since CDL07-08 just without any video interludes.
Big problem I have with this concert's footage so far: Why the heck does the
entire main concert segment sound like Ayu was muted out!? It only got fixed during the encore singing segments...

I wonder when they shortened the Alice dress. About You's dress also appeared to be longer and without the tutu.
