"9" stands as a remarkable example of modernization without sacrificing authenticity. It often gets overlooked, akin to "Dehumanizer," another underappreciated gem. Balance is a key element. Mercyful Fate, a genuinely eerie band, skillfully balances between the creepy and the campy. Their complexity and ability to navigate beyond song structure norms distinguish them. King Diamond's performance showcases more humanity, injecting emotional depth into the theatricality. Despite some production quirks and minor songwriting issues, "9" delivers spine-chilling moments through its lyrics and enunciation. It may feel more modern than "Melissa" and "Don't Break the Oath," but it remains intelligently crafted classic metal, demonstrating an awareness of the contemporary metal scene without compromising their signature style. Mercyful Fate's awesomeness endures, making it a mistake to overlook "9" by categorizing it as part of the band's "later stuff."
