Hi!
I will talk to you about my favorite band, Mayhem, that is a nordic band from Norway, with four integrants, Atila (vocals), Necrobutcher (bass), Blasphemer (guitar) and Hellhammer (drums). They are the precursors of this style in this country and the world. They play Black Metal, the hardest and darkest kind of metal.
I like this band because their songs are very interesting for me, I had always listened to this kind of music, and I like how Blasphemer plays his guitar very much. He does it very well.
My favorite song of this band is "the freezing moon", however, there is not satanist, only talk about dark and nature. The people think that those songs are satanic, but this album  is about the dark nature completely.

Here is a link from "the freezing moon" studio version.
