Dating from punk’s early days, L.A.’s Flesh Eaters have enjoyed an episodic existence, with a revolving lineup around singer/songwriter Chris D. They fuse aggressive punk with splashes of blues, rockabilly, and boogie amid D.’s apocalyptic-noir ravings. The band’s 1981 lineup, featuring members of X (John Doe, D.J. Bonebrake) and the Blasters (Dave Alvin, Steve Berlin, Bill Bateman), was its best, and that crew recorded I Used to Be Pretty, the Eaters’ first album in 15 years, and has hit the road. The veteran all-star cast ensures Pretty’s originals and covers glow with caustic charm. Porcupine, with ex-Hüsker Dü bassist Greg Norton, opens.
