Jeebus nobody seems to like my Chris... Come on, now, you can't possibly listen to "Outshined" by Soundgarden and NOT be chilled to the bone by how his scream just peels the paint off the walls in your mind. There's nothing like it. Or how genuinely touched and erotically aroused one feels after his stirring performance of Ave Maria...
I''ve not heard enough Rage Against the Machine to realli judge Zack at all, but as far as vocals go, Chris Cornell is just one of the best.
The other best male vocalist out there??? Serj Tankian.
