-- there's "Song of the Ancients / Fate" -- timed nicely near the end with the near-end sequence involving Devola, Popola, and then Emil being heroic.
But from there you should be able to find the rest of the concert. Before it gets pulled down. And if S-E keeps pulling it down, hopefully it's because they plan to sell a bluray, which I will instantly buy.
A post from Emi on facebook suggests that she may, indeed, be doing some additional work on Automata, just not the theme song (the live concert HAS that song, by J'Nique Nicole, and it's veeeeery good!)
Thought y'all would want to know, since NieR is like, one of the best things to happen to VGM. IMO. And I like to think I'm right.
