Music of Xenogears

The soundtrack of Xenogears consists of 45 pieces of music, 42 of which were instrumental. It also includes a choral song in the Bulgarian folk style with lyrics written by Tetsuya Takahashi, and two other lyrical pieces performed by Joanne Hogg with lyrics written by Masato Kato. All tracks were composed by Yasunori Mitsuda. According to Mitsuda, the music was composed with strong influences from traditional music, especially Celtic music. The music has had several official releases as well as arrangement albums and a concert.

Xenogears Original Soundtrack
The Xenogears Original Soundtrack is the official soundtrack to Xenogears. It was originally released on 2 CDs in Mar 01, 1998, exclusively published in Japan. It was rereleased on Apr 04, 2018 as Xenogears Original Soundtrack Revival Disc -the first and the last-, with differently localised track titles. In addition, the track Premonition was included (which was not on the Xenogears Original Soundtrack — however, confusingly, a different track was named Premonition on that release). Four vocal remixes of existing tracks sung by the Irish choir ANÚNA were also arranged for the Revival disc.

CREID
The CREID album consists of ten tracks from the Xenogears Original Soundtrack, rearranged by Yasunori Mitsuda in a traditional Celtic style. It was released in 1998, and again in 2005, on a single disc.

-MYTH- The Xenogears Orchestral Album
The MYTH album is an orchestral arrangement of 14 tracks from the Xenogears Original Soundtrack, released on a single disc in February 2011 and on vinyl in April 2011. Arrangements were done by Yasunori Mitsuda, Youki Yamamoto, Sachiko Miyano, and Natsumi Kameoka. The performance was done by the Bulgarian Symphony Orchestra, and Joanne Hogg reprised her role for the arrangement of Small Two of Pieces.

Xenogears 20th Anniversary Concert -The Beginning and the End-
The Xenogears 20th Anniversary Concert was a concert held in April 2018, featuring orchestral arrangements of the Xenogears soundtrack, as well as performances of certain tracks from the Revival disc and CREID. Arrangements were done by Yasunori Mitsuda, Sachiko Miyano, Mariam Abounnasr, and Youki Yamamoto. A Blu-ray disc recording of the concert was released in 2019.
