Thanks for the pg.99 stuff! I've been looking for their stuff for ages, seems it's mostly out of print
Here's three albums of dark, brooding hardcore stuff:November Coming Fire - "Dungeness"
Naming their band after a Danzig song, and their album after the most grim location one could wish to see (a barren headland in the southeast of England, consisting of a large shingle beach, a road, a powerstation, and a few driftwood shacks), it's obvious from the start that November Coming Fire aren't going to be all sunshine, kittens and lollipops. "Dungeness" combines the hardcore rage of Converge with the atmospheres and dark, ominous chord progressions of post-metal, and to great effect. If they hadn't broken up shortly after its release, these guys would be leading the UK underground right now.
Planes Mistaken for Stars - "Up in Them Guts"
Whiskey-soaked, bleak-as-you-like, heavy post-hardcore. The absolutely oppressive "life-is-fucked" attitude and atmosphere is present on all their albums, but none more so than this, in my opinion their best. Strangely, despite the downbeat tone of their music, I briefly met Gared O'Donnell, the vocalist, and he's a proper cheerful, friendly bloke. Which I guess makes it even more impressive that he's able to conjure up such a shitstorm of sheer doominess on record.
Plate Six - "Anthems for a New Republic"
I actually bought this off the back of a pretty vague, but very positive review I read in a magazine, and the fact that it has cool artwork and was going for ONE PENNY on amazon. Kinda hard to get into to start with, and I'll admit I only very occasionally listen to it, but when I'm in the right mood, it's great. Sounds like Fugazi on downers, playing inside a cement mixer.
