So basically I'm just going to go through a series of artists I discovered either directly or indirectly through last.fm, and prattle on about how great they are.
Doom Metal band from the UK. I obtained two albums - Halcyon, and New Dark Age. Both are brilliant. The title track from the latter album appears to be based in Lovecraftian lore, which just awards it bonus points. Highly recommended for anyone with a taste for epic Doom.
Yeah, I know, heretical for me to say it, but I'm really not a great fan of their work with Messiah. This may admittedly be due to me viewing Marcolin himself as an utter douchebag. That said, Epicus Doomicus Metallicus, Nightfall, From the 13th Sun, and everything from King of the Grey Islands onward are all bloody fantastic albums. Lowe absolutely kicks ass in his place as the new 'Mass vocalist, as he does in every band he features in.
