You can Vote for Most Valuable Lead Vocals (Rock Groups)

Talking HEads and David Byrne hit teh scene in ~ 1977 or so. Such a unique style! Think of all teh New Wave acts that followed and sounded kinda like him and Talking Heads but failed to take it any further really.   Mostly interchangeable with a few exceptions.

When the singer is also the main songwriter that ups his stock a lot I would say.   The winner probably has to wear both hats largely in their group.

Keith Lancaster - Acappella

I like the lesser known votes. Gives me something new to check into.   

Morrissey- The Smiths.
