YES to fast rapping, like RME. It would also be interesting to hear him do kind of a "yelling" aggressive song, kinda like Sabotage or GATS, where it's not really clean singing, but just like "yelling over guitars" as Mike's playlist name puts it. He's not gonna scream like Chester, but he can kinda employ a raspy sound when he wants to. You can hear him do it when he raps hard in By Myself live, or when he does the "blood is pouring" line live. It's not comparable to Chester's aggressiveness obviously, but he could pull of some lead aggressive vocals. Hopefully we get a little bit of everything. And I would hardly call that screaming in STB. It just sounds heavily distorted, and it only sounds close to screaming when Chester says "riiiiiiiight".
I like how you talk about Mike's loud voice and don't mention No Roads Left. [youtube]-mchhPf81iw[/youtube]
