best rock voices

Roger Daltry/ Pete Townshend
Jeff Beck ( In know... he doesn't sing. But the sounds he gets out of his guitar .... ! Check out this CD : Jeff Beck's Guitar Shop, and you'll know whay I mean. )

Ronnie James Dio Rainbow Black Sabbath Dio
Bruce Dickinson Iron Maiden

Dfrigovt that was Jim Dandy Mangrum, though I'm not sure of the spelling of the last name. I saw them in concert in 1978 opening for Blue Oyster Cult.

I'm pleasantly surprised to see several mentions of Ronnie James Dio. He is definately the best singer in heavy metal, and possibly in Rock and Roll! There are many others that I like, but are not really great singers, but that's why there are so many different answers here. Although I have to wonder if the guy who suggested Bon Scott was serious or still under the influence???

I still like Ian Andersons voice. I like to listen to Bob Dylan, but I'm not sure that makes him a good singer!?!

Geoff Tate, lead singer for Queensryche.

Jon Anderson, Lead Singer for Yes.

Just to name a few.

Many of the names mentioned here are worthy, I'd like to add Chris Cornell and Jimmy Barnes. Barnes has amazing technique, he can sing with more strain than anyone, do it all day and not wind up hoarse.
