Try out Ruins of Beverast - Unlock The Shrine. The first song has a real Xasthur vibe. After that there's tons of original ideas. It's a wonderful album.I'd love to find more in that vein if you've got any suggestions. No matter how many times I burn through the Xasthur catalog, as soon as I get to that track I stop what I'm doing and just let it wash over me.
