Hm... Conor brings up a good point about the "extreme" genres of metal. Bands like Esoteric, Disembowelment, Xasthur, Khanate, Thergothon and Skepticism appeal to a very small but dedicated audience so it's hard to say.
As for an addition to the list, I would add Absurd Existence. An excellent German death/doom metal band who had only released one album named
Angelwings. If you're into the likes of My Dying Bride, Novembers Doom and Opeth, I'd say you'd like it. [img src=\"style_emoticons/[#EMO_DIR#]/wink.gif\" style=\"vertical-align:middle\" emoid=\"

Another addition would be Symbyosis. A technical death metal group hailing from France. Most bands in this genre just emulate Suffocation's sound but these guys have their own sound with plenty of atmospheric parts and memorable solos (rather than most of these bands that just use guitar noodling to show off). If you're looking for some modern death metal that isn't total garbage, pick up
Crisis. [img src=\"style_emoticons/[#EMO_DIR#]/wink.gif\" style=\"vertical-align:middle\" emoid=\"
