Duck. Little Brother, Duck!'s second and final full-length, Don't Take Our Filth Away, explores numerous strains of underground rock fauna throughout it's 45-minute runtime. Over the course of ten tracks, the Portland, Oregon four-piece tease apart fragments of math rock, emo, noise rock, and screamo, recombining them into a knotted, vibrant evolution from their sprawling 15-song debut Survival Is Not a Workout. Guitars converse with one another in the stereo field, stopping on a dime as if to change the subject, and then squeal with feedback into downtrodden passages that spontaneously erupt with euphoric abandon and introspective complexity. Vocals alternate between prominent gang-sung wails and buried-in-the-mix screams, constantly shifting the contours of the band's already serpentine writing style. Although the band's final album-length statement, Don't Take Our Filth Away's densely arranged, erratic compositions provide ample paths to lose oneself, and keep returning for years to come.
