Haha, Cock and Ball Torture! just like The View of Everlast
Seriously, I guess u could check out Vintersorg's "The Enigmatic Spirit" and maybe the rest af the "Cosmic Genesis" album since you seem to like his voice.
I would also highly recommend Arcturus "La Masquearde Infernale" where Simen (ICS Vortex) & Garm (both previously in Borknagar) sing together on a few songs. Arcturus latest album "The Sham Mirrors" is also great
