Christopher Guest is a good one along those lines too, even though he is in a lot of movies, he can do a lot of different voices effectively.

billy zane in demon night, his voice is awesome in that movie!


singer wise at this point in time it's a girl named cassie!

Dont forget Michael McKean either.

Hell Spinal Tap is just damn talented :)

How could i have forgotten this one?!?! One of the greatest voice actors ever:

The Late Great Phil Hartman

I still have a hard time believing he is gone, even though it has been almost a decade.

I'd have to say Glenn Danzig

Yeah. I couldn't believe that when that happened. Still depressing to think about.

Another one for Vincent Price.

Freddy Fucking Mercury.

Oh, and Martin Landau when he does Bela Lugosi.

And Vincent Price, doing anything.

O ya Neil Young.
