Corey: (about his Brainiac voice) If I speak very softly, Brainiac is really just my own voice kept at a very low level. That's it-easiest job I ever had. Everyone tells me the voice is "brilliant" and I'm really doing nothing-I'm just reading very quietly. Some of the most satisfying stuff for me to listen to are my tracks as Brainiac. It's like, "That's so cool! That's how he should sound!"
