(sorry, I had to split it because I exceeded the 20000 characters limit
Third, the albums I liked a lot:
Aenaon - "Cendres Et Sang"http://grooveshark.com/album/Cendres+Et+Sang/7168616
Gem and instant classic of progressive black metal from Greece. Lots of variation, including pianos, lazz parts with sax, psychedelic keyboards, electronic touches, growls, powerful clean voices, riffs that get stuck on your head for hours and a cover of "In Heaven". I think the highlight must be "Black Nerve", but every song has a lot to discover.
Altar Of Plagues - "Mammal"http://grooveshark.com/album/Mammal/6111804
Black metal with post-metal like never before!
Ära Krâ - "Ferne Tage"http://aerakra.bandcamp.com/
New German "black metalcore" band with lots of personality. That accordion on "Neuschnee" (L)
The Atlas Moth - "An Ache For The Distance"http://grooveshark.com/album/An+Ache+For+The+Distance/7167073
Errrr... post-metal-core or something like that. Lots of emotions and certain epic atmosphere that makes it irresistible.
Avernal - "Réquiem Para Los Rebeldes"http://grooveshark.com/album/R+quiem+Para+Los+Rebeldes+Necrolog+a+Parte+1/7385498
"Huacalera" amazing song I listen on repeat. Free album on the band's page on Don't Pay Music: http://dontpaymusic.com/avernal/
The Book Of Knots - "Garden Of Fainting Stars"http://grooveshark.com/album/Garden+Of+Fainting+Stars/6651032
Unclassifiable avant-garde. Sometimes it gets close to post-metal and then it goes anywhere.
Boris - "New album"http://grooveshark.com/playlist/Boris+New+Album/65505866
They make pop. Pop to have fun.
Carnal Disfigurement - "Inhuman Devoured Content From Cranial Cavity"http://grooveshark.com/album/Inhuman+Devoured+Content+From+Cranial+Cavity/7387743
Extremely dirty mid-tempo brutal death metal. You listen to it and you imagine you are swimming on sewer fluids surrounded by rotting corpses, AND YOU LIKE IT.
Clinging To The Trees Of A Forest Fire - "Visceral" demohttp://grooveshark.com/album/Visceral/6888071
and the split with Nesseria:http://grooveshark.com/album/Clinging+To+The+Trees+Of+A+Forest+Fire+and+Nesseria+Split/7395787
They denomite their sound as "funeralgrind" and list bands like Khanate and Disembowelment as their influences. With that, you can begin to imagine how rotten, heavy and dissonant this band's music is
Corrupted - "Garten Der Unbewusstheit"http://grooveshark.com/album/Garten+Der+Unbewusstheit/7319272
Sludge with funeral doom with acoustic. Beautiful new album from these Japanese guys.
Craft - "Void"http://grooveshark.com/album/Void/7363403
Well done black metal misanthropy.
Dephosphorus - "Axiom"http://grooveshark.com/album/AXIOM/6808272
Devin Townsend Project - "Deconstruction"http://grooveshark.com/playlist/Devin+Townsend+Project+Deconstruction/61104862
Weirdness knows no limits on this progressive avant-garde metal album. Lots of collaborations by known artists like Ihsahn, Fredrik Thordendal, Mikael Åkerfeldt, Floor Jansen and more. Devin GENIUS. The concept of the album is hilarious X-D
Dining In Tuscany - "1556"http://grooveshark.com/album/1556/5943156
More black/grind, mixed with ambient parts. Nice number.
Fuck The Factshttp://grooveshark.com/playlist/Fuck+The+Facts+Die+Miserable/65457742
The riffs and Mel's screams trap you in a vortex of violence from which it's hard to escape.
Gallhammer - "The End"http://grooveshark.com/album/The+End/6204829
These Japanese girls released another great and twisted black/doom/crust album.
Gigan - "Quasi-Hallucinogenic Sonic Landscapes"http://grooveshark.com/album/Quasi+Hallucinogenic+Sonic+Landscpaes/6535203
Very trippy technical avant-garde space grindcore.
Gridlink - "Orphan"http://grooveshark.com/album/Orphan/5930657
How the hell did they manage to pack SO MUCH violence in an album just 12 minutes long is beyond my comprehension.
Jenny Hval - "Viscera"http://grooveshark.com/album/Viscera/6004580
The mere fact that she was Shellyz Raven's singer makes me like her music immediately. Experimental and very intimate music from Norway, leaning to neofolk.
The Kilimanjaro Darkjazz Ensemble - "From The Stairwell"http://shop.tkde.net/album/from-the-stairwell
and the live album "Live - I Forsee The Dark Ahead, If I Stay"http://shop.tkde.net/album/live-i-forsee-the-dark-ahead-if-i-stay
I think I liked the live album even more than the studio one. Let there be oniric jazz for a long time! And let's not forget about...
The Mount Fuji Doomjazz Corporation - "Anthropomorphic"http://shop.tkde.net/album/anthropomorphic
The new album of the drone project of the same people. I loved it, too.
Krallice - "Diotima"http://grooveshark.com/album/Diotima/6080155
The mix of mathrock and black metal goes on! I liked it even more than their first album!
La Última Canción Del Mundo - La Última Canción Del Mundo (2011)http://laultimacancion.bandcamp.com/album/la-ltima-canci-n-del-mundo-2011
Big local pride! The most passionate band in Rosario and surroundings!
Mitochondrion - "Parasignosis"http://grooveshark.com/album/Parasignosis/5567364
Twisted, insane, chaotic, experimental and EVIL death metal.
Midnight Odyssey - "Funerals From The Astral Sphere"http://grooveshark.com/album/Funerals+From+The+Astral+Sphere/7380854
Experimental and trippy space black metal.
Neoandertals - "Ebu Gogo Gutting The Child"http://grooveshark.com/album/Ebu+Gogo+Gutting+The+Child/7395310
Grindcore? Death metal? Done only ith bass and drums, a weird album that refuses being classified.
Nightbringer - "Hierophany of the Open Grave"http://grooveshark.com/album/Hierophany+Of+The+Open+Grave/6925345
Full-speed black metal with lots of psychosis.
Norska - "Norska"http://grooveshark.com/album/Norska+2010+/5124867
Great riffs await you here!
Nyogtha - "Hymns To The Astral Planes"http://nyogtha.bandcamp.com/
Space drone ambient.
Origin - "Entity"http://grooveshark.com/album/Entity/6434243
"Expulsion Of Fury" ringtone of the year. I've woke up with that song eveeryday since the album came out.
Peste Noire - "L'Ordure à l'état Pur"http://grooveshark.com/album/L+Ordure+L+tat+Pur/6563519
Another of the French bands that carry the flag of experimentation in black metal produces a new very varied and weird album that includes burps and cackles.
Reido - "-11"http://grooveshark.com/#/search?q=reido+-11
After a long wait, this album divided opinions and I was left on the "I loved it" side.
Rwake - "Rest"http://grooveshark.com/album/Rest/7395336
Great new album by this classic band of experimental sludge/stoner.
Septic Mind - "
I think this could have been Esoteric's new album if they didin't soften. Tremendous funeral doom.
SubRosa - "No Help For The Mighty Ones"http://grooveshark.com/album/No+Help+For+The+Mighty+Ones/5998374
All-female sludge/stoner band. This album takes you to the desertic areas of the U.S.A. It's the two violins and the voice who lead the music.
The Sullen Route - "Apocalyclinic"http://grooveshark.com/album/Apocalyclinic/7258488
Another case of bad name for a very good album. They used to play traditional death/doom, but this album is simply doom with lots of personality.
Tangled Thoughts Of Leaving - "Deaden The Fields"http://grooveshark.com/album/Deaden+The+Fields/6956254
Post-metal with future jazz. Very beautiful.
Terra Tenebrosa - "The Tunnels"http://grooveshark.com/playlist/Terra+Tenebrosa+The+Tunnels/65499188
More experimental black metal, mixed with ambient.
Total Fucking Destruction - "Hater"http://grooveshark.com/album/Hater/7395413
Funniest grindcore album of the year!
Trance To The Sun - "The Blue Obscurities"http://grooveshark.com/album/The+Blue+Obscurities/7394743
It had been quite some time since I got so hooked on a gothic music album (post-punk/darkwave), but there a very personal sound here.
Ulcerate - "The Destroyers Of All"http://grooveshark.com/album/The+Destroyers+Of+All/5567034
These New Zealanders continue to show why they are one of the lead bands in modern death metal. Even if I like their previous album more because it's more groovy, this one is more experimental and atmospheric.
Unexpect - "Fables Of The Sleepless Empire"http://grooveshark.com/album/Fables+Of+The+Sleepless+Empire/6325098
The other ultra-bizarre avant-garde metal of 2011. A lot more coherent than the previous one, which ended up being intolerable.
Universe217 - "Familiar Places"http://grooveshark.com/album/Familiar+Places/6342175
Experimental doom with a great female voice.
Vanessa Van Basten - "Closer To The Small/Dark/Door"http://grooveshark.com/playlist/Vanessa+Van+Basten+Closer+To+The+Small+Dark+Door/65509662
Excellent instrumental Italian band that plays some kind of very varied post-rock/doom/avant-garde, adding acoustic guitars, piano, sax, keys, sound effects and electronic noises. Extremely beautiful, calm, MAGIC. A gem I recommend to everybody.
Vektor - "Outer Isolation"http://grooveshark.com/album/Outer+Isolation/7327243
I didn't know there was a thrash metal as original as this one!
Virus - "The Agent That Shapes The Desert"http://grooveshark.com/album/The+Agent+That+Shapes+The+Desert/5751423
True Norwegian avant-garde metal! STRANGE.
Will Haven - "Voir Dire"http://grooveshark.com/album/Voir+Dire/7135951
Ufff, this is HEAVY! Hardcore/sludge/post-metal/Meshuggah, all in one.
*Shels - "Plains Of The Purple Buffalo"http://grooveshark.com/album/Plains+Of+The+Purple+Buffalo/6284717
6v6 - "Les Byes Mystiques"http://grooveshark.com/album/Les+Byes+Mystiques/7395869
This year I discovered witch house with White Ring y Salem, and then I listened to this French group.
