All of the music for the "Wolf's Rain" soundtrack was composed and arranged by Yoko Kanno. The vocal songs are performed by various artists, including Maaya Sakamoto, Raj Ramayya, Ilaria Graziano, Steve Conte and Joyce, and they were recorded around the world, including Japan, Poland, Brazil, the United States, and Italy to offer a diverse range of music and give the soundtrack an international flavor. Two CD soundtracks, produced by Yoko Kanno, Toshiaki Ota, and Shiro Sasaki, were released in Japan by Victor Entertainment.
