Dol Goldur and Stronghold are exellent, epic albums but I've not yet managed to get hold of Nightshade Forests, I think I'll have a look on ebay for that stonker.
Talking of music binges, lately I've been listening to a lot of Pig Destroyer and Morgion (yes quite a contrast). Just got the new PD album "Terrifyer", such a good release, personally I think it's easily topped Prowler In The Yard and I've never been able to get enough of "Cloaked By Ages, Crowned In Earth", such a masterpiece of an album.
