Falcom Sound Team jdk (Falcom sound team Jay Dee Kay / J.D.K. / Falcom Music Staff / JDK Band / Nihon Falcom) is a Japanese music composition team of Nihon Falcom Corp. The name of the group appears on all of Falcom’s soundtrack releases rather than crediting composers by name. Falcom was also a pioneer in video game music, with their early soundtracks mostly composed by chiptune musicians Yuzo Koshiro and Mieko Ishikawa, and some arranged by Ryo Yonemitsu. They were the first company to produce game music CDs, the first to apply vocals to game music, and one of the very first to have their own sound team composed of professional musicians dedicated to games, the Falcom Sound Team jdk. Falcom’s Ys soundtracks in particular are considered some of the finest and most influential role-playing game scores of all time.
