I haven't listened that much metal, but to name a few:
-Nachtmystium, love the atmosphere of their songs, linked track for example. I have so far focused on Silencing Machine and Black Meddles pt. 1&2.
-Sólstafir, I had really hard time finding their songs and albums after listening them for example on Spotify, I mean ''Svartir Sandar'' wasn't that hard, but album like ''Í Blóði Og Anda'' or song ''Þín orð'' were bitches to find afterwards.
-Lamb of God, because killer basslines, fun to play
