Jun Senoue, Kenichi Tokoi, and Fumie Kumatani on Sonic Adventure Original Sound Track:

Crank the Heat Up!! …for Final Egg

Senoue: This is the music arranged in my own style based on track 25 [Mechanical Resonance …for Final Egg] and is a satisfactory finish personally. The intro’s odd meter, the wah’s melody, the intertwined bass solo…. Oh yes, the guitar in the middle sounded with a cheap and small guitar amp worth of around 5,000 yen. Anyway, the keyword in myself was “thoroughly and nastily.” I did the work at an external studio, so I was impatient to let Tokoi listen to it quickly.

Tokoi: It’s exactly the image of the final stage. It intertwines with avant-garde guitar’s phrase and the slap bass that appears in the middle is fitting.

Kumatani: And then this is the impression that the old man who had become short of money were hurry-scurry afterward? Did I make the image expand too much again for this?

Senoue: If that were the case, would it be the impression as if he were chased and caught by a debt collector…?
