ah fuck it, I'll just make an EDUCATIONAL post based on all criteria of interesting conceptual works.
Allerseelen - Gotos = Kalanda
Genre: Industrial
This very low-production industrial album from Allerseelen focuses on a poem cycle based on the twelve months of the year called "Gotos = Kalanda" by early 20th century German rune initiate Karl Maria Wiligut. While fairly underdeveloped musically (indeed, Kadmon re-recorded many of the songs again for later albums with better production) and anyone who doesn't like industrial music very much would be sure to hate it, it IS extremely interesting for the occult element.
Belborn & Rose Rovine E Amanti - Grain
Genre: Neo-Folk
This was just released this year, but I like the concept that it's advertised as (It's pretty decent as a folk album too):
"Grain is very powerful and well known symbol all over the world. It stands for life, fertility, love and renewal. Its spiritual strenght is very present in Christianity and Paganism. Despite different beliefs, two great neo-folk acts - German Belborn and Italian Rose Rovine E Amanti are united in idea of grain, a something new has arisen. A split of 13 rare, unpublished and brand new tracks, 54 minutes of outstanding music. CD in digipack. "
Burzum - Hliðskjálf
Genre: Ambient
Varg Vikernes did a great job of creating soundscapes to go along to stories in Germanic myth, which are narrated in the liner notes. Best read together with listening for full enjoyment.
Cold Fusion - Occupatria
Genre: Martial Industrial
The soundtrack to living in an occupied fatherland. Harsh military ambient, industrial.
Empyrium - Weiland
Genre: Neo-Folk
Weiland is split into three chapters, each to pay homage to a specific nature mystics: Moorland, Forest, and Water. The music is really cool too.
Fields Of The Nephilim - Elizium
Genre: Gothic Rock
I have no idea what this album is really about, but I better add it in anyway because it RULES. Something about finding "some kind of heaven".
Lux Occulta - Forever Alone. Immortal.
Genre: Black Metal
Forever Alone. Immortal. is a concept album based on the path of Luciferian enlightenment. From the beginning rebellion to the final suicide, the music is epic, triumphant, desperate, sorrowful, failure and despair.
Old Man Gloom - Christmas
Genre: Ambient/"core"/doom metal
Old Man Gloom isn't so much a concept album band, rather than they're a concept band in themselves. Apparently they write about a sci-fi universe with something to do with Apes.
Today Is The Day - Sadness Will Prevail
Genre: Metal/Hardcore/WTF
This is seriously one of the hardest albums to listen through start to finish. It is seriously emotionally crushing, as well as physically uncomfortable to listen to. Double album, almost 80 mins to each disc. Raw intensity and despair. Needs to be experienced to be understood.
Various Artists - Infernal Proteus (4CD + Book)
Genre: Various
Infernal Proteus is a four disc compilation put out by The Ajna Offensive in which many artists pay homage to various plants that mean something to them. Along with the music is included an art book with full colour illustrations and plates to accompany the music. Music ranges from ambient, to neofolk, to psychedelic rock/metal
Venetian Snares - Rossz Csillag Alatt Született
Genre: Breakcore
This album is about being a pigeon in Hungary, as a vast oversimplification because explaining the rest would require more examination. Maybe a pigeon in Hungary on cocaine outside a symphony house.
