Glenn Danzig - Astonishing vocalist and so underrated. Will never be considered as one of the all time greats because of the subject matter, but he just doesn't care and does what he wants. Badass outlaw artist.
Ian Astbury - As with Danzig he's extremely underrated. The Cult are a phenomenal band that deserve to be right up there with the biggest rock bands.
Burton C. Bell - Amazing dichotomy. The first time I heard Fear Factory I thought they had two singers.
Chris Cornell - Now that's a powerful voice.
