I’ll agree with Maynard and Layne. Although I haven’t heard Chris Cornell (at least, not knowingly), I’ll agree with you on those two guys.
My nominations (barring the obvious like David Gilmour and Roger Waters) are: David Draiman (Disturbed) Gackt (Malice Mizer and solo projects)
Lead singer of Dir en Grey. Man, that guy can sing and scream. Just listen to the song “Merciless Cult”!
Lead singer of System of a Down Jesus Christ, he can sing.
I don’t know some of their names, but here they are:
Howlin’ Wolf Aretha Franklin Hitomi Yaida
Lead singer for: Queens of the Stone Age The Yellow Monkey Globe (no, not the French dude) The Tiger Lillies
I heard the guy in Audioslave and he sounds like he could eventually be great–but probably needs another 10 years. The guy in the Queens of the Stone Age is probably roughly the same age but has already hit it.
That’s Chris Cornell, formerly of Soundgarden, and he has been around since the late '80s. That’s not really the kind of music I listen to anymore, but I’ve always thought he had a striking voice and an amazing range.
