A fresh, young rock-and-roll sound has tumbled into the Twin Ports from deep inside Carlton County. It’s the Langertsons, a teenage four-piece made up of sibling pairs Josie and Audrey Langhorst and Amri and Eli Gilbertson, all of Mahtowa. The group performs catchy alt-rock power-pop that feels bright, smart and new. In 2018, the Langertsons released their second full-length album of original material called “Flower Crowns and Imagination.” It was recorded at Sparta Sound with Rich Mattson. The band promoted the release with in-studio performances at KAXE in Grand Rapids and KUMD in Duluth.
