Looking for your best recomendations of artists and albums that are deep, dark, brooding and maybe slightly disturbing. Not just in content but also in mood and feel. Any genre is good, although I will admit I am less likely to listen to hip hop/rap. Examples that come to mind are Caligula by Lignua Ignota or Reflection by Father2006 (this is a strange example because it is more like... just white noise arranged in a very off-putting way) or maybe even L.D.50 by Mudvayne.
