Back in June, Grimes announced on Twitter that she has “a new song coming out on the suicide squad soundtrack,” that would be titled “Medieval Warfare.”
The avant-pop star premiered her contribution on Zane Lowe’s Beats 1 radio show, which you can listen to below. Additionally, Lowe aired a short interview with Grimes, who is currently on tour in Europe. She told him how the song came about: “It was an old demo and then I just tailored lyrically and sonically a bit more to what I thought they would want for the movie.” Grimes shared her inspiration for the song:
“To be fair, before they even hit me up about this song I watched the trailer at least 20 or 30 times. I don’t know, it’s Harley Quinn and the Joker. It’s pretty iconic characters. It’s not like a movie that you don’t know anything about it.”
