Sorry to double-post, but I had a very interesting series of dreams last night and it included a performance of "reconstructing a full picture" to open a FictionJunction performance (this was a joint FJ/Yuuka event in one concert).
The parts included from high to low - Wakana, Yuuka, Hikaru, Keiko, and the echo was Miss Kaida. (No, I don't know where Kaori was, and I was very surprised upon waking up and thinking back.) I was also surprised at this order as, had I been awake with a vision like this, I'd have done Miss Kaida, Wakana, Hikaru, Keiko; Yuuka. However, Yuuka and Hikaru's nasal potential is on par with eachother I'm sure, so.
Everyone was scattered on a completely dark multileveled stage with a spotlight specifically assigned to highlight them when they sang and immediately cut off. During the "sontilia deta, ilfio--" part you can hear in the sample, everyone starts ominously walking on beat (I mean half-speed, beat 1 and 3) across the stage (akin to the live 2016 Tsuioku performances if you remember which I'm talking about, I'm not good w/ specific concert names).
Their dress was very neo-Gothic-Aristocrat, countering their usual simplified lolita and femme-dandy-inspired (this depends on which singer we're talking about) FJ wear, though Hikaru was in harem pants laced across the front and a regular-sized crooked tophat, which I enjoyed. The colors were very Marchen-esque (black, white, beige, little gold, not unusual).
