The Shins’ music has always had a Swiss watch-like quality to it: Seamless from the outside, hypnotically intricate when you open it up. Heartworms, their first LP in five years, bridges the electronic textures of 2012’s Port of Morrow with the jangly, cerebral pop of Chutes Too Narrow, touching on psychedelia (“Painting a Hole”), country (“Mildenhall”), and synth-pop (“Cherry Hearts”). It's the band’s most adventurous album yet.
