Hear a preview of the epic John Wick: Chapter 4 soundtrack

Composer Tyler Bates admits that he and writing partner Joel J. Richard had to seek help from the internet to fully understand the script for the Chad Stahelski-directed John Wick: Chapter 4 (out March 24).

"I, personally, am not a martial artist, and I am not an authority on kung fu," says Bates, who, with Richard, has composed the scores for all four films in the Keanu Reeves-starring action franchise. "I had to have Google open the whole time. I kept Googling all these different weapons that were referenced that I'd never heard of before, just so I understood a little bit more about the specifics of what was happening visually. The script should probably have a glossary at the back of it, because there's a lot of detail in it, and that comes truly from Chad Stahelski, and his passion and his commitment to martial arts."

The film's soundtrack album is released digitally March 24 and kicks off with the instrumental "Big Wick Energy." Who was responsible for that title? And did they take the rest of the day off after thinking of it?

"That would be Joel, my composing partner," says Bates, whose many other soundtrack credits include 300 and Guardians of the Galaxy. "Joel's like my brother, and when we score the John Wick films, we share our music, and that inspires conversations and inspires new ideas, [but] at the end of the day, when it came to naming all the tracks, I deferred to Joel."

The album features pop star-turned-John Wick: Chapter 4 cast member Rina Sawayama on the single "Eye for and Eye" and Bates' daughter Lola Colette on a new version of the Martha and Vandellas' hit "Nowhere to Run." Bates also collaborated with the band In This Moment for a song titled "I Would Die for You."

"'I Would Die for You' is a song that I wrote with Maria Brink and Chris Howorth of In This Moment and [also] produced," says Bates. "Chad, literally, out of the blue, called me up, and he's like, 'Yo, Tyler, do you know this singer, I love her, Maria-something, she's in this band, In This…?' I'm like, 'In This Moment?' He said, 'Yeah, that's it!' I said, 'I'm actually working on their new record right now. [Laughs] They are real fans of John Wick, which is really cool."

With John Wick: Chapter 4 clocking in at just short of three hours, Bates and Richard were tasked with producing a lot of music for the film, whose cast also includes Ian McShane, Donnie Yen, Bill Skarsgård, and the late Lance Reddick, among others.

"Chad prefaced sending the script to Joel and I with a desire to expand the scope of the score, because the scope of the film had increased so broadly," says Bates. "I wasn't totally imagining that we would create a two-and-a-half hour score! It's the longest score that I've ever done in my career."

This might be a cheeky question, but does Bates get paid by the minute of music he produces?

"Hell, no! Are you kidding?" he says. "It's definitely time to get another job. But to be part of something like this is such an honor and a privilege. Music means so much to Chad, and he's a real rocker, but he also loves classic film scores, and classic movies, and it was really great to be able to imbibe the appreciation of all that with him. He's marching to his own beat and I love that about him. He's a disruptive filmmaker and any time that a filmmaker is willing to step out on the plank like he does, I'm all in."
