For those whose knowledge of Swedish artists starts and ends with ABBA, Avicii, and Swedish House Mafia—shame on you.

More than worthy of inclusion on the list of internationally recognized Scandinavian bands is First Aid Kit, the 10-year project of Stockholm sisters Johanna and Klara Söderberg, for both the quality of their music and their steadfast staying power. With the release of their fourth album, Ruins, the pair have married their low-key acoustic fingerpicking to mature country, weaving their near-identical vocals and phrasing in a way that’s far closer to dusty Nashville than to the quaint folk of their coastal hometown.

Playing the sold-out Vogue Theatre on Saturday (January 27), the duo are living proof that only the best bands break North America.
