How did some of the greatest singers from the 80s get their massive range and power? I've noticed there tends to be a consistency with tone too - it DOES sound like a lot of open throat is used but I'm not sure. I've just listened to songs like Stone in Love - Journey, Valerie - Steve Winwood, Lonely Boy - Andrew Gold etc obviously there's a lot more. Did these people really stumble upon the correct techniques? Or did they have coaches? It's interesting to see how popular vocal styles have changed over the last 20 / 30 years!
