As the title suggests, this is a darker, more hardened affair for the South Korean crew. On , slow it down, boost the low end, and amplify the menace on six tracks that align with their vampire-themed web series, Dark Moon: The Blood Altar. Lead single "Bite Me" is a speaker-rumbling highlight that pops and rattles as the group invite listeners to "Come kiss me and bite me." Further action is encouraged on another imperative, "Sacrifice (Eat Me Up)," a wobbly, midtempo slow burn. The explosive, riff-packed "Karma" is the rowdiest they get on this collection, which favors ominous vibes and atmospheric dread over anything else. Upon release, topped charts in Japan and South Korea, while entering the Top Three in Europe and the U.S. ~ Neil Z. Yeung
