Calvi's new venture is the first taste of new Calvi material since last year's Hunter.

Speaking to NME about the new score, Calvi said, "It’s exciting. It’s been hard to not talk about it. It’s incredible to be part of something like this. It’s a whole new thing for me, but it felt completely natural. Bizarrely, I feel like I can really relate to the characters. It was a really good fit. I’ve always loved the show – everything about the way that they dress, the music that they feature, how strong the characters are and how filmic it is. It’s just much better than most things you see on TV."

Expanding the creation of the score, Calvi added, "What’s been really fun is to write lyrics for Tommy [Shelby] and to really get into his mind,” she said. “It’s been really interesting to write as if I was Tommy and really believe in this character. I really got lost in that, as if he was real. When you’re writing a soundtrack, you’re watching something all day. I was dreaming about Peaky Blinders and got completely obsessed. That’s how it should be."

Calvi also explained how her sound differentiates to that on Hunter, "The sense of beauty with brutality is something I’ve always been interested in exploring with my music. What was exciting to me was how to demonstrate that with the guitar. I took a lot of inspiration from Westerns, because I do see Peaky Blinders as a Western set in Birmingham."
