Well, I admit I've only heard a little from their stuff(mostly the prog. death metal) so thanks for enlightening me(and destroying the myth in my country that most death metal vocalists can't sing).
I might even finally check 'em out. :tongue:

Do check them out, I don't think you'll regret it.

Also, there's (the afore mentioned Devin Townsend) Peter T?gtgren of Hypocrisy with his solo project Pain which is sung mostly clean (and not too bad either). And even further, there's Ihsahn, the vocalist for the black metal band Emperor, with his selftitled soloproject also being sung clean mostly (and quite well, too).

I don't have a single favorite, but I would say Triptykon is close. I think Tom Gabriel Fischer really hit the nail on Eparistera Daimones.

My favorite track off the album is this one: http://www.youtube.com/watch?v=R9d0Ov6gyNs

Not that they're death metal, but Corey from Slipknot can jump from the nastiest death-growl to the sweetest singing without breaking a sweat. I love his voice! I wouldn't call Slipknot a "favourite band", but I loved their past two albums and think they're underrated: people are very snobbish until they hear them and say, "Actually, they're pretty good".

Actually, I think my favourite music-source lately is this site: http://www.rockabyebabymusic.com/ecom2/index.php/music/rockabye-baby-lullaby-renditions-of-metallica.html
