These are the albums I've listened to the whole way through at least twice from 2013. I don't tend to listen to a bunch of shit I don't want to listen to so this list is generally confined to bands/albums that pique my interest somehow. Feel free to toss recommendations my way.
October Falls - The Plague of A Coming Age (8) (Dark Folk/Pagan Black) Mikko Lehto's new album is even more focused on the dark folk and nostalgic pagan elements than his recent prior work. Shorter track lengths have increased accessibility. Clean 'epic' sounding vocals are used in some parts. Haven't decided for sure if those add to or detract from the overall feel.
Autism - The Crawling Chaos (8) (Post-Rock/Spoken Word) Excellent post-rock performance featuring spoken word vocals reciting excerpts from H.P. Lovecraft's short story "The Crawling Chaos".
The Ocean - Pelagial (8) (Instrumental Post-Sludge) This album is much better without vocals.
In Vain - Ænigma (8) (Extreme Progressive) My natural inclination when listening to any band for the first time is to make comparisons to other bands I'm familiar with. My first thoughts were of Enslaved and Opeth as well as De Profundis' recent album I heard a while back. The one that stuck however was Enslaved but with a strong death metal influence.
Redwood Hill - Descender (8) (Post-Black/Post-Metal) Very well executed amalgamation of post-black and sludge elements. They keep it short and sweet on this debut album, clocking in at 37 min and change.
Anciients - Heart of Oak (6) (Progressive) Takes the style and sound of Baroness and Mastodon and makes a competent if uninspired album.
Shining (NOR) - One One One (6) (Extreme Progressive/Avant-Garde) Norway's Shining has pulled back on the insanity and relegated the sax to occasional solos. This album comes off closer to the works of Devin Townsend than their own Blackjazz.
Universe217 - Never (6) (Experimental Doom) Didn't care for the Rob Halford/King Diamond style vocals but the instrumentation makes the album worth listening to.
