"With each body of work, with each album, or with each song, actually, one has to find the right voice with which to deliver the song at its best.
Now, with this new record, it was very, very difficult to find what voice to deliver such words with, because obviously these words have a great deal of weight. They have very strong narratives. They're very much action-on-the-ground storytelling, the witness to the action on the ground.
I needed to find a voice that didn't add more weight to the weight that was already there, and it took a lot of experimentation to find the voice. To begin with, I tried approaching singing it with what I would call my full voice, which is a 41-year-old adult woman voice and it destroyed the words. It was far too strong, much too weighty, because the words already have that.
So gradually, through a process of elimination and mistakes, I finally came across the voice that you're hearing, which you're rightly describing as a very high, very simple voice. It was - I was looking for something that was almost characterless, that could just be the narrator of the story, almost disembodied from the action, just relaying what they can see happening, and that voice had to be very, very simple, very pure, very high, to inhabit almost a characterless place within the scene."
