The music was recorded in Bulgaria by the Sofia Philharmonic Orchestra; the recording, which took place at the Bulgarian National Radio Studio, included roughly 130 musicians and choir. A European orchestra was chosen as Makino wanted a distinctive sound different from the typical Hollywood-styled orchestral sound. The recording was supervised by Thomas Böcker and his company Merregnon Studios, who were brought aboard the project by Harmonics International based on their previous collaborations on Symphonic Fantasies concerts. Rock elements included in some tracks were recorded in Japan by guitarist Tenyu Nakamura and drummer Tatsuya Suzuki. As much music as possible was recorded live rather than using synthesized instruments. The game's theme song was "Into Free -Dangan-", written and performed by Japanese rock duo B'z. The song was an English cover version of B'z's 1998 single "Samayoeru Aoi Dangan". The lyrics were written by Koshi Inaba and Shane Gaalaas, while the music was created by Tak Matsumoto.
