Forget brutality--Pyrrhon deal in ugliness. On their second album, the Brooklyn quartet bioengineers a hybrid of death metal, grindcore, and noise that channels The Dillinger Escape Plan, Cobalt, and even early God Forbid. Seasick guitar leads dance dizzingly around patches of crushing, steady riffage, accompanied by frenetic drumming and vomited vocals that range from malevolent shrieks to tortured moans. The resulting nine songs are discordant and unpleasant, but deeply compelling, with numbers like "Invisible Injury" and the sprawling final title track leaving an impression on the listener deeper than a prenatal deformity.
