Underoath's first two albums reverberated in the rock world, but music this hard gets little mainstream attention. Album three blurs those lines with its alluring, experimental production. If you don't know what E-bows and reel bows do to a sound when stretched by delays and effects pedals, then "just push play." The dichotomy between hoarse growling vocals and gliding melodic trips is dizzying. "To Whom It May Concern" is the best one-slice sampling of this inventive screamo.
