Jun Senoue and Kenichi Tokoi on Sonic Adventure Original Sound Track:
Choose Your Buddy! -Slap Bass ver.-
Senoue: This music during the character selection has things recorded with separate playing methods called slapping and fingerpicking for the bass. This slapping method is crisp and I like it. Taneda’s bass is my favorite. Let’s do it together again, OK~!!? By the way, slapping and chopper [alternative term for slapping in Japanese] mean the same playing method.
Tokoi: What I thought after seeing the recording … is that this person (Bassist Taneda) isn’t a human being. I like this “Whoop whoop” slap bass extremely.
