Fumie Kumatani, Kenichi Tokoi, and Jun Senoue on Sonic Adventure Original Sound Track:
Kumatani: I had worked hard. All were samples, but I continued to be particular about it at any rate from kinds of percussion instruments to singing voices. But now, it becomes the music I’m highly satisfied of.
Tokoi: Honestly, I used to be shocked when listening to this. Eliminating the pointless chord feeling in the vocal part and the way of using the important chord feeling and timbre that appear in other parts in making the atmosphere of the music…. I think each of them is very perfect.
Senoue: Certainly~. This is a piece concerned with finding out the materials and with composition ability of integrating those.
