"I referred to the original 'Suspiria' film," explained Yorke. "It was an odd process from the beginning. When they first came to see me, the producers and [editor] Walter [Fasano], I just thought they were mad, because I've never done a soundtrack before. And 'Suspiria' is one of those legendary soundtracks. It took a few months to even contemplate the idea." 

Despite his reservations, Yorke eventually agreed to do the film, but opted to go in an entirely different direction with his take. 

"I watched the original film several times, and I loved it because it was of that time, an incredibly intense soundtrack. Obviously Goblin and Dario worked incredibly closely when they did it together," Yorke said. "But it was of its time and there was no way I could reference it in any way. There was no point, other than what I found interesting was they used repetition of motifs, again and again and again. Part of your mind was saying, 'Please, I don't want to hear this anymore. That was really great. There's a way of repeating in music that can hypnotize. I kept thinking to myself that it's a form of making spells. So when I was working in my studio I was making spells. I know it sounds really stupid, but that's how I was thinking about it. It was a sort of freedom I've not had before. I've not worked in the format of song arrangement. I'm just exploring."
