Ill try my best to describe it (if you cant help me ill understand)
it starts with a steady rhythm and bassline followed by a girl singing and then it turns into a whole different thing. Things go quiet and then she starts singing something like "sundown (or someone) the sky blablabla" and repeats while the melody uplifts and keeps building up like ayumi's-appears(armin van buuren's sunset dub) and then you know the drill (everything goes crazy).
