Interviews
Key quotes and excerpts from GDC 2011, MDCAST, Inverse, Waypoint, and Digital Foundry.
GDC 2011 - "Memories of a Composer: Creating the Streets of Rage Soundtrack"
Koshiro's GDC 2011 talk is the primary source for almost everything known about the composition process for the Streets of Rage trilogy. He discusses his custom sequencer, his genre influences, and the specific techniques used to achieve the SoR2 sound.
"I was listening to a lot of European club music - techno, house - while I was composing Streets of Rage 2. I wanted the soundtrack to sound like it could actually be played in a club."
- Yuzo Koshiro, GDC 2011 (paraphrased from talk summary)
"I built my own sequencer for the Streets of Rage games. This gave me much more direct control over the sound chip than using the standard Sega driver would have."
- Yuzo Koshiro, GDC 2011 (paraphrased from talk summary)
The full talk covers the composition process for both SoR1 and SoR2, the technical constraints of the YM2612, and Koshiro's perspective on game music composition as an art form. The GDC Vault recording is publicly accessible and is the recommended primary source.
