Nier Gestalt/Replicant had a woman invent an entire language that she never revealed to anyone and use it to sing the entire soundtrack.
Drakengard 1 took short 6-15 second clips of classical music, layered and warped them, and created a soundtrack that was meant to make you intentionally feel like you were going insane the entire time (it worked).
Taro has been using music in progressive and interesting ways long before Automata.
