Swedish country-folk sister duo First Aid Kit burst onto the scene—seemingly out of nowhere—five years ago with their second album The Lion’s Roar, exemplifying a warm, captivating studio sound that most veterans would love to attain. And they did so by taking music back to basics: Top-notch harmonies, mixed with down-home storytelling and apt metaphors about relationships, sounding as if they were plucked straight out of California in the ‘70s. Ruins is the band’s fourth album and continues down that same path but, this time, there’s a maturity shining through, where life isn’t as rosy as it may have once been. Most songs exist in a mid-tempo range, with gorgeous orchestral flourishes throughout, and many explore a longing for someone else—someone who was once there but now is clearly gone. On album opener “Rebel Heart,” they look inward, singing, “But I know you truly saw me/ Even if just for a while/ Maybe that’s why it hurts now/ To leave it all behind.” The pedal-steel lined “Postcard” wrestles with falling for someone, parting ways and the complicated feelings you have when you’re trying to let go. And on “Distant Star,” those sentiments are echoed once again, as they declare, “But you’re a distant star/ My darling you’re so far away/ You were never meant to stay.” But that’s what ruins are—memories of something that once existed, a physical reminder of something great you can point at, yet know isn’t quite the same. First Aid Kit’s Ruins is kind of like that.
