Unknown from M.E. …Theme of “Knuckles”

Kenichi Tokoi, Fumie Kumatani, and Jun Senoue on Sonic Adventure Vocal Mini-Album:

Unknown from M.E. …Theme of “Knuckles”

Tokoi: This fourth song counted from prototype has changed considerably. It seems that the rap with “wicked feeling” has become quite a topic.

Kumatani: Everyone imitates this rap part “Knock-knock, it’s Knuckles…”, right? The rhythm as if the body would move naturally and the seemingly tongue-twisting bass are very cool. This song has the feeling of “that composer’s thing.”

Senoue: Marlon Saunders takes up the appointment continued from NiGHTS’s a cappella and Burning Rangers, doesn’t he? Now that you mention it, the melody might certainly have “Tokoi” feeling…. Come to think of it, do you know what the title’s M.E. is? It seems to be the abbreviation of Master Emerald.
