Geheimnis is a stunning, one-man Black Metal band from Brazil, led by a character called Count Belial. This tape, Das Negras Montanhas, reminds me a bit of older Judas Iscariot. It was released by Gungnir Productions in 2005 in limited quantities. That means that you don't have this, unless you are really kult. Fortunately for you, I am, but not too kult to share.
