Kind of obsessed with this quote from Henry Jackman, the composer for Winter Soldier, about writing the Winter Soldier theme:
“Because there’s a human element to the Winter Soldier that gets revealed toward the end of the film, the Winter Soldier starts off unrelenting and brutal and mechanized and almost Terminator like but the difference between The Winter Soldier and Terminator is that somewhere behind the wires and all the mechanization is a character that we know and we care about and that more importantly, Cap knows about and it’s very painful to him.
So one of the things I ended up doing with the Winter Soldier was I spent literally ten days just on production with vocals because I wanted to get the sensation of a human trapped inside machinery. So I did a lot of vocal recordings and then processed the living hell out of them to get these tortured, time-stretched human cries of someone who has been so processed that it’s become mechanized at the same time but you can still hear the human in there.”
