Robert Plant

I see at the top every comment has to do with how beautiful and sweet her voice is. Guess what, plenty of singers have beautiful and sweet voices. Know one could yell and change their tones like Robert Plant. So many people have tried, none have managed. Come on people... Immigrant Song? Black Dog? Can't beat that voice as far as uniqueness goes... You CAN'T.

If you actually listened to his works, ranging from Led Zeppelin to his collaboration with Alison Krauss, you can actually see (or hear, really) that he has the screechy, emotional, and loud voice, essential to hard rock, and actually has this gentle, soothing, and well-toned voice, much of "conventional" singing voice. His vocal range is amazing and he is definitely not given enough credit for his versatile vocal ability.

Robert Plant easily belongs in the top three in this category. Remember, back in 1969 nobody had ever heard the high pitched primeval wail. Probably the most influential rock singer ever. God, how many painfully inferior imitators did Plant inspire. It's a long list. Extraordinary power and range, Plant is a giant among rock singers, and a true icon.

The singer for the greatest rock band of all time. His screechy yet somehow enjoyable voice is immediately recognizable. God I love the Zep...

I thought this is the top ten most UNIQUE singing voice ever? If that's the case, Robert Plant should definitely be there. No one sings like him. Back in the seventies he was the number one singer in the world. And he could reach higher notes than most women can. Pure legend.

You might notice the scarcity of Zeppelin cover bands

It was a close one between Robert Plant and Freddie Mercury, but Robert's voice is very distinguishable. There is nobody else that sounds like Robert Plant. Mercury a close second.

An unique, powerful and awesome voice for the singer of the best band ever!
Why he is not higher in this list, he is just a legend...

LED ZEPPELIN for ever!

This list is an absolute joke. The singer of the best rock band in the history of man. His vocals tried to be imitated but couldn't be replicated.

Robert Plant's voice is a musical instrument that only he can play, and boy does he play it! He belongs much higher up on this list.

Everyone knows his voice.
Even if they're not familiar with LZ, they're like "Oh, I know this guy! I recognize led zeppelin. "

Amazing! Just listen to Immigrant Song or Black Dog and you'll realize how unique his singing voice is.

When Robert Plant comes on the radio, whether with the yardbirds, or post Zeppelin you know it's him.

This has to go to Robert Plant people can pull of Freddy just a bit but Robert Plant is just crazy.

Most unique tone of voice ever. And best rock singer ever. This guy was simply amazing.

No one in the world can sing like Robert plant. Or even come close.

His falsetto distinguishes his voice from the rest
