Musically, the album is influenced by classical and Romani music. While reading page five of the script, Zimmer came to a part about a Gypsy fortuneteller. He called the director, Guy Ritchie, and told him they needed to take a road trip to Slovakia. Zimmer felt that it was appropriate to reflect the Romani culture in his music. Zimmer got two Romani bands (Cigánski baróni and Kokavakere Lavutára – Sendreiovci) to record the score for the film, resulting in the score for the film as envisioned.
