Chico, California sludge metal veterans whose 2026 album THE EARTH IS BREATHING BENEATH ME delivers tectonic heaviness. The all-caps title and nature-as-threat imagery fit their brand of environmentally aware, apocalyptically heavy sludge.

Los Angeles power metal project whose 2024 single Fat Man — likely referencing the atomic bomb — pairs military nomenclature with explosive heavy metal from the City of Angels.
