Metal is often a game of one-upsmanship. Metal bands have a tendency to cram as much hyperbole into their song titles or band names as possible. So when a band called Mammoth Grinder comes along, there’s a good chance they want you to believe they’re the most gnarly badasses in the universe. It’’s not entirely without merit, though. Mammoth Grinder play a pretty burly style of sludge metal that’s not particularly fancy or progressive, just meaty, loud and as heavy as it gets. and sometimes, that’s really all you need.
