Black Metal mixes with everything and anything these days, and mixed results will happen. It is like part of the color wheel, it can be add to anything, but the results vary depending on what it is mixed with. You have blackened crust punk (Young and In The Way), Post-Black Metal (or Black Shoegaze as I called it, with Deafheaven), traditional black metal (if I don’t love me some Emperor) and black metal meets arena rock ( the new Black Anvil I can NOT get enough of and is in my top 3 for record of the year).
Let me tell you young’ins something you will learn actually fairly quick, and Coalesce said it best with an album title: There is nothing new under the sun. Let me repeat that for those skimming through my shitty, ADHD, virally infected writing and say it louder, since reading may be too good for you: THERE IS NOTHING NEW UNDER THE SUN! This has been true for a while, but goddamn, you can at least do a good job at making the music and kicking ass. Those bands I mentioned above do very well with what they have and their ideas and their mixture of genres.
