And to be honest, I don't know anything about Kerry Ellis, so I exclude her, and because of her style is not to be a frontman, is other style.
I mean, Joni Mitchell or Laura Nyro did a kind of music not to be act on stage like a frontwoman.
Tina Turner with the Ikes was a brilliant frontwoman, and later also. Or Janis Joplin, but because of her style of music was more agressive, more soul, old R&B, or rock.
