Slithering through dimly lit passageways, “Urgency,” found on the self-titled debut from dark-pop collective She Policeman, creates an anticipatory sense of unease. Those creeping-beyond-the-shadows vibes are further accentuated by the spectrum-morphing, sensory overload of its video’s colorful, shape-shifting display. Catch the record release and debut performance from She Policeman this Friday, March 3 at Boot & Saddle with Purples and Langor.
