Well, i am into many genres, but mostly Black Metal, in the not-so-extreme way.
To name a few bands (Though it is hard):
Exiled From Light (Dark, a little downtempo black metal, from New Zealand).
Funeral Mourning (Very slow, haunting tones, from Australia).
Nortt (Very down-tempo, haunting, and a little ambient, from Denmark. Some of the songs, like Hjems?gt (Haunted, in english), are perfect for TES games!).
Trancelike Void (Hypnotic, Acoustic instrumental Black metal, from Belgium. Can recommend this to anyone! Especially Ghost Mountain).
Else, i really like Buckethead. An instrumental guitar virtuoso, who excels in both relaxing acuostic melodies, and up to lightning speed scales. Listen to the Acoustic Shards album. He recorded it, while he was... 13, i think?
I could ramble on for a 100 more bands, litteraly, but i think this should be enough, so you actually don't get tired reading (hopefully listening).
