The music in the concept art glimpse is probably not gonna be in the game. I think they had it in there to set the tone and all. Then they will have some music from the game itself. You agree?
Speculation of course but the music could of been from one of the levels? People were up in arms over the “Mass Effect” music playing over the trailer because it didn’t have the “London Orchestra” behind it.
I believe that the “mass effect” like music was fitting for the concept work. Putting in loud, orchestrated music would have ruined it.
