Yuzo Koshiro composed the Streets of Rage and ActRaiser soundtracks — widely regarded as the finest FM synthesis music ever written for a game console.
Yuzo Koshiro began composing game music while still a teenager, working on Dragon Slayer (1985) for Falcom before founding Ancient with his sister Ayano Koshiro in 1990. His early work on the Ys series demonstrated an extraordinary grasp of the PC-88's sound hardware; the Ys I & II soundtracks are among the most acclaimed of the 8-bit era. When the Sega Genesis became his primary platform, Koshiro's compositional style evolved to exploit the YM2612 FM synthesis chip in ways that Sega's own composers had not attempted. He programmed his own custom music driver rather than using Sega's standard tools, allowing him to produce sounds and rhythmic patterns that the hardware was not intended to generate. The Streets of Rage 2 soundtrack (1992) is the definitive statement of his Genesis work: a fusion of house, techno, and industrial music that sounded nothing like other game scores of the era and genuinely competed with contemporary dance music for sonic sophistication. ActRaiser (1990) on SNES took a different approach — classical and orchestral pastiche for a game about a god rebuilding civilisation — demonstrating Koshiro's range across electronic and pseudo-acoustic styles. He has continued composing through multiple hardware generations, adapting to each platform's capabilities with the same technical mastery that defined his Genesis work.
