"Opus of Extinction" by Saponification (Based in San Francisco, California) is the premier full length offering from the band, and represents an assembly of the bands evolution from a more slam driven death metal self titled EP, to more fast paced Brutal Slamming Death Metal style in the veins of Vomit Remnants, Severed Savior and Visceral Disgorge. Every track on the album encapsulates different pulses of groove, technicality, and brutality that some listeners will not anticipate coming. From gutturals to high pitch ear splitting squeals, mid 2000's era technical guitar riffing mixed with modern slams, to blistering blast beats and bone crushing breakdowns, this Opus has something for every Extreme Death Metal enthusiast.
