“Well, a goodbye never seems finished”, sing Klara and Johanna Söderberg on “Distant Star”. Written in the shadow of Klara’s split from her fiancé, much of their fourth album examines the difficulty of moving on, delivering despair and confusion through breathtakingly pure harmonies. For all the lyrical reflection, there’s a keen sense of forward thinking within the music. “Postcard” and “Distant Star” may offer exquisitely classic Americana, but the duo also draw on dream pop (“Fireworks”) and rippling electronic (“My Wild Sweet Love”) before squeezing a brass band and rowdy, closing-time chorus into “Hem of Her Dress”.
