Jun Senoue and Fumie Kumatani on Sonic Adventure Original Sound Track:
Azure Blue World …for Emerald Coast
Senoue: I wonder if I feel, Actually, this music has been this long, hasn’ it!!?…. I also had something which Kumatani sang, “Lalala~,” in the mid version. With the fact that it is Sonic’s first action stage, I tried to decide on a piece with melody that is easy to get used to.
Kumatani: La~ Lala’la~
Senoue: Yes, yes. By the way, the instrument playing the melody is an electric sitar.
