From watching that video you posted of Arch Enemy I gotta wonder about the shape that chick's larynx must be in. But ya know... I'm demoing a vocal processor in my studio and it has a setting that makes my voice sound just like hers. Hmmm, I wonder if she's piping her voice through an effects pedal of some sort.
But thanks for the post Graham and keep on 'rocking in the free world.'
