Australian duo An Horse harkens back to the ‘80s jangle pop of so many college radio bands — and those who never made it that far — but it’s a sound well worth revisiting. Guitarist/vocalist Kate Cooper and drummer Damon Cox deliver wistful, irresistible pop tunes, with simple, propulsive guitar rhythms, bright tambourines and a big, driving drum sound. Cox’s back-up vocals pair beautifully with Cooper’s strong but plaintive voice, and the songs are carefully structured with a tightly wound energy that occasionally breaks for air without losing momentum. There are a number of standouts (the see-sawing “Camp Out,” the emotionally fiery “Company” and “Little Lungs,” the tense “Postcards,” and the hyperkinetic “Horizons,” to name a few), but Rearrange Beds is packed throughout with indie pop of the highest quality; even the lyrics are smart and sweet, and will hook even the most jaded. Cooper pounces on top of bass drum lines with lyrics like “I believe in horizons now” and “Oh my God, you’re a handful!” matching syllables to martial beats with vigor. You’ll be doing the same before long.
