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
desoto
no contest here- TWISTED SISTER!!!

ok, Robert Plant of led zeppelin.

female- janis of course.
Might catch some flack here but I always thought Freddy Mercury of Queen had amazing range and a unique style of his own.
This could be a long list if you want to include the entire history of rock. Some possible nominations might include:
Elvis Presley; Chuck Berry; Roy Orbison; Jerry Lee Lewis; Jim Morrison; David Clayton Thomas; John Fogerty (the lead singer for CCR); Janis Joplin; Mick Jagger; etc. Can you narrow your definition a bit?
