This album’s introductory cut is the barely 30-seconds long “Boo,” a neat little soundscape that uses jingling sleigh bells, children’s voices and a locomotive whistle to mimic the sounds of kids playing too close to a railroad crossing. The implication is that a terrible accident is about to occur, but thankfully the scare ends without incident, only giving the listener a harmless sonic boo.

Sarah Snavely and her brother Jacob are Dag för Dag and like with “Boo,” they display here throughout a penchant for the noir-ish side of life. Just about every song has a touch of the experimental with songs like “Boxed Up in Pine,” sung by Jacob, sounding especially otherworldly thanks to a haunting melody that Sarah plays on violin.

Sarah and Jacob both sing on “Silence is the Verb,” a dark number that sounds like what you might hear if you played the B-52s at half-speed. The same mired-melody effect works nicely on “Light on Your Feet” where Jacob sings at the pace of someone who’s just taken a Quaalude and on the grunge-less but grunge-inspired “The Leather of Your Boots.”

Equal parts shoe gaze, ambient experimental and quirky alt-pop, Boo is full of songs that are unpredictable – these are not quick to cozy up to sing-a-longs. But a little bit of a challenging listen is what Dag för Dag is going for, and those who “get it” won’t mind one bit when all the subtle hooks whisper “boo!”
