Kenichi Tokoi and Jun Senoue on Sonic Adventure Original Sound Track:
Tokoi: Above all, what I was puzzled over was making the conga’s rhythm and the bongo, which are doubly overlapped, intertwine without incompatibility. It became a completion particularly having the mix of Akashi-san…. The improvised piano is also comfortably audible.
Senoue: With just the starting rhythm becoming audible, I feel the image of Chaos comes to appear. In that sense, I think it became an effective introduction.
