 Chrono Trigger proved a great success , and the soundtrack proved extremely popular with fans . Mitsuda claims that it is his " landmark " title , which " matured " him and his music . He attributes its success with fans to his use of folk and jazz styling , rather than the " semi @-@ orchestral " style popular in game music at the time . Following Chrono Trigger , Mitsuda composed the soundtrack for Front Mission : Gun Hazard , again with Uematsu . According to Uematsu , Mitsuda again worked so much that he eventually defecated blood out of stress and physical problems . Mitsuda worked on three more titles for Square : Tobal No. 1 ( Square 's first PlayStation game ) and Radical Dreamers : Nusumenai Hōseki both in 1996 , and Xenogears in 1998 , which featured the first ballad in a Square game , the Celtic ending theme " Small Two of Pieces " sung by Joanne Hogg . Mitsuda also during this period produced albums of arranged music of his original scores , creating acid jazz remixes in Chrono Trigger Arranged Version : The Brink of Time and a Celtic arrangement album of Xenogears music , Creid . In July 1998 , following up on what he had said in his original interview with the company , Mitsuda left Square to work as a freelance composer , the first of several of Square 's composers to do so .
