Yuzo Koshiro

Yuzo Koshiro was born on 12 December 1967 in Japan. He began composing professionally at age 16–17 when he joined Nihon Falcom, contributing to games including Dragon Slayer II: Xanadu (1985). His scores for Ys I: Ancient Ys Vanished (1987) and Ys II (1988) are among the finest examples of late-1980s FM synthesis composition, celebrated for their melodic sophistication and emotional depth.

In 1989 Koshiro composed the Mega Drive score for Revenge of Shinobi, demonstrating his command of the YM2612 FM chip. By 1990 he and his sister Ayano Koshiro had co-founded Ancient Corp, the studio through which his most iconic work would be produced.

The Streets of Rage trilogy (1991–1994) brought Koshiro to worldwide recognition. Streets of Rage 2 (1992) remains his masterpiece - a fusion of techno, house, and industrial music unprecedented on the Mega Drive, composed using a custom sequencer Koshiro built himself.

His SNES score for ActRaiser (1990) demonstrated extraordinary versatility: where the SoR trilogy was club-influenced and electronic, ActRaiser was cinematic and orchestral. Koshiro continued composing through the Etrian Odyssey series (2007–present) and contributed to Streets of Rage 4 (2020).

Koshiro's catalogue divides naturally into three phases. The Falcom era (1984-1989) produced the Ys scores on PC-88 FM synthesis - tight, melodic compositions that helped define the action-RPG sound. When he left Falcom and co-founded Ancient Corp with his sister Ayano, the Mega Drive era began: Revenge of Shinobi (1989), Streets of Rage (1991), Streets of Rage 2 (1992), and Streets of Rage 3 (1994), plus the Arabian-themed Beyond Oasis (1994).

Running alongside the Mega Drive work was ActRaiser (1990) on the SNES - a score so orchestrally ambitious it surprises listeners discovering it for the first time. Where everything Koshiro wrote on the YM2612 FM chip was electronic and club-influenced, ActRaiser was cinematic and sweeping, demonstrating a compositional range that the Streets of Rage trilogy alone would not have revealed.

The modern era begins with the Etrian Odyssey series (2007-present), which brought Koshiro back to high-profile RPG scoring after years of lower-profile projects. His return to the Streets of Rage world with Streets of Rage 4 (2020) confirmed a legacy still very much active.
