Keep in mind that a good vocalist doesn't necessarily need a wide range...vocal pyrotechnics are impressive, sure, but it's only one of several ways to impress. Some of my favorite vocalists have a pretty narrow vocal range, but they interpret their songs like no one else. John Lee Hooker, Bob Dylan, Howlin' Wolf, Muddy Waters (lots of blues singers here), Johnny Cash.

To me, a vocalist with a wide range has an edge on the competition. But a vocalist known primarily for having a wide range? That's a lot like a hotshot lead guitarist--spectacular, yes, but heart and soul will always win out over spectacle.
