Diamond Head's "Coffin Train LP" unwittingly resurrects the ironclad spirit of heavy metal while subtly poking fun at its own grandiosity. The title track winds through darkness, alternating between sinister hooks and sly nods to the genre's glorious past; an ambitious balancing act that works because it refuses to take itself too seriously. "Belly of the Beast" serves as both a rallying cry and a cheeky wink, as Brian Tatler conjures riffs that resurrect the very foundations of metal, making you wonder if they've improved the formula or just painted over it.
