Christian Alvestam--He was their singer, but was kicked out last year. He currently does side projects(Miseration, Solution .45 etc.) One of the best growlers ever! He can go as low as Cannibal Corpse and scream as high as Psycho from Gloria Morti! oh and he sings MAGNIFICENTLY! It's a true rarity to find an amazing singer that can growl/scream.
Dani Filth--One freaky, creepy, sketchy, weird dude in a messed up band. I don't care for C.O.F. due to their lyrics and imagery, however I have some clean songs from them and ...wow Dani can scream better than anyone. He sounds like a demon gypsy from Mordor or some crap. I love his voice sooo much! He's unreal..
**Note: Not my favorite vocalists, rather whom I find unique. Some are my favorites tho :p **
