Honorable mentions (I have enjoyed these a little bit too much :)
Misery Index has once again delivered, The Killing Gods is amazing, super heavy, and somewhat simple but still complex on so many levels.
Killitorous released their debut Party, Grind. Killitorous approach to the genre is comedy and they seem to have a lot of fun. The album is pure joy, both on a spiritual and technical level.
