The Xenogears Original Soundtrack is the official soundtrack to Square's role-playing video game Xenogears. It was composed by Yasunori Mitsuda and contains 44 tracks, including a Bulgarian choral song and two pieces performed by the Irish singer Joanne Hogg. Though the game was released in both Japan and North America, the album was published in Japan exclusively as a two-CD set on March 1, 1998.
