[the mourner13]

Till Lindemann (Rammstein)!!!!!
Jonas (Katatonia)
Devin Townsend (DTB, SYL)
Gavin (Dredg)
Ben (Sybreed)
Dez (DevilDriver)
Alexx (Eisbrecher)
I.C.S. Vortex (Arcturus, Dimmu Borgir)

Dez really destroys in Devildriver although I didn't like the band so much.He's much better than Lamb of God's singer...

 

[katatonikk]

Yeah LOG sucks. Randy's vocals sound like they're coming out opf a butthole.

 

[EternityRites]

To add a little femme to this poll:

Elisabeth Toriser - Dargaard
Syrah - Qntal
Azam Ali - VAS
Julie Xmas - Battle of Mice ( also Made Out of Babies)
Tori Amos

Now back to the metal..

-Most Interesting or Dynamic Metal Vocals-
Disclaimer - I am not all that impressed with operatic male vocals in metal music, and this is in no particular order:

Steve Von Till (Neurosis)
Jonas Renske
Mikael Akerfeldt (Opeth)
Joe Duplantier (Gojira )
Kyo - (Dir en Grey)
Freddy Lim (Chthonic)

Favorite vocalist of all time->
Hyde (L'arc en Ciel)

(edit) as I was reading this to my boyfriend he had to taunt me with Megadeth, so I will add that Dave Mustaine is my most hated metal vocalist ever.

 

[L0bster]

while speaking of femme, two of my all-time favorite singers:
Billie Holiday
Nina Simone

I still havent found any female metalvocalists of my liking, but Agnete M Kirkevaag from Madder Mortem did sound promising, havent heard much of their stuff.

 

[salient]

My depressive top 5:

1. Jonas Renkse.
2. Mark Hollis.
3. David Sylvian.
4. Chuck Schuldiner
5. Vincent Cavanagh.

 

[Hypnos]

Freddie Mercury was surely not my favourite vocalist, but he definitely was the best one

 

[Jesse Pohjalainen]

Jonas
Ville Valo
Ville Laihiala
Bruce Dickinson
Neil Young.

In no order. That's the current state of opinion.
