The Music of Ys: Falcom Sound Team jdk
The first sound of Ys was written by an eighteen-year-old. Yuzo Koshiro composed most of Ys I, with a handful of tracks by Mieko Ishikawa; for Ys II the ratio inverted, Ishikawa carrying the bulk of more than fifty songs while Koshiro contributed signature pieces including "To Make the End of Battle." Between them they wrote melodies that players have hummed for nearly forty years.
From late 1988, Falcom folded its composers into a collective: Falcom Sound Team jdk, founded under Ishikawa's leadership. The house rule, unusual then and now, is that the team signs as one: individual track authorship is officially unrevealed, a deliberate tradition meant to make the music belong to Falcom rather than to stars. The separate jdk BAND, first active 1990 to 1996 and revived in later forms, is the performing arm, contracted musicians who play the catalogue live and on arrange albums.
