Concept albums can be dicey, but this Brighton, England electro duo negotiate the terrain smartly, crafting the most appealing musical ode to zombies since Thriller. The Underworld-ish “Feed on You” and horror-movie march “How Do We Stop the Normals?” set the spooky tone amid ever-present washes of minor-key synths. But beats that throb, stomp, whip, and crack, plus a diverse parade of guest vocalists (underground MCs El-P and Beans, cowpunk howler Emily Breeze, and Bernard Sumner doppelgänger David AutoKratz), steer the proceedings well away from the novelty bin.
