King Gizzard & the Gojira Wizard

Recommendations from Chris:Death Metal:Amon Amarth - Twilight of the Thunder God (Viking Metal)Cynic - Focus (Death Metal with heavy jazz influence)Dethklok - Dethalbum 1 to 3 or Galaktikon (Same artist, different pseudonym, very tongue-in-cheek)Opeth - Ghost ReveriesPersefone - Aathma (Really solid Andorran Prog/Melodic Death Metal band, one of my favourites of2017)Xerath 1 to 3 (Death/Groove with added orchestral parts)

Groove Metal:Lamb of God e.g. SacrementMastodon e.g. LeviathanMeshuggah e.g. Catch Thirty-ThreeMonuments - The Amanuensis (Born of the "djent" movement like Tesseract, but more focus on groove and melody)

Recommendations from Robert:King Gizzard & the Lizard Wizard - "Nonagon Infinity" & "I'm in your Mind Fuzz"
