Howling Sycamore - Seven Pathways To Annihilation ...this one has taken a while to really sink in, but it's a great album. Superficially very similar to the debut, it sticks with the same melodic palette and general riffing/drumming/vocal style, but it's quite a bit more complicated, both in the way the parts are layered and in terms of song structure. Not as immediately catchy, but deeper and maybe more rewarding.
Deathspell Omega - The Furnaces Of Palingenesia ...these guys took the opposite route this time. These songs are more streamlined and less chaotic than their other recent albums, I daresay even "accessible" by DSO standards. It pays off -- nothing feels dumbed-down or commercialized here, but the riffs are allowed to breathe and build "organically" into memorable sections. Less of a maelstrom, more of a nicely paced, enjoyable trudge through pervasive gloom.
I always have trouble finding a third album for this thread. Don't have one at the moment.
