I find myself falling in love with more post-metal and blackgaze acts like Cult of Luna, Boris, Jesu, and Deafheaven usually, but Between the Buried & Me, Opeth, The Dillinger Escape Plan, Converge, and the new Chelsea Wofle albums (lol) are all essential too.
I dig a lot of other bands involved with prog metal, death metal, black metal but more in the vein of Leviathan, Blut Aus Nord, or Negura Bunget, drone/doom metal, and probably some djent and metalcore, but all the metal sub-genres all something interesting to offer, even though I've kind of dissociated with trash for the most part since the only two good Metallica albums are Ride the Lightning & Ride the Lightning (Remastered) and I only really like a few albums by Slayer/Megadeth. And even though Iron Maiden, Black Sabbath, and whatnot are always legendary, the born in the wrong generation culture that surrounds them anymore prevents me from liking them in a way.
