best rock voices


looking for nominations for best rock voice, NOT best vocal performance.......looking for the rock-quality of the voice itself........my first obvious choice is the ORIGINAL Rod Stewart

Jennifer Knapp is a christian Rock singer. Not well known, I suppose, but in my estimation she has an incredible vocal style & attitude that fits the best rock voices criteria.
Shelby Lynne is not so easily caste, but if you like she is best known as a country singer.
Though certainly not classified as a classically pure voice, one that superbly fit the style of their music was Little Feat's Lowell George.
