Give me a reason and I'll prove ya wrong ;P But, yeah, I'm not talking vocal power here, I'm talking vocal range and consistency.

This is a song from a solo project of Bruce Dickinson (lead sanger Iron Maiden) showing that power and consistency can go very well hand in hand. Considering Iron Maiden practically is the most mainstream New wave of British Heavy metal band it's one of the purest forms of metal out there.
