First it was Alaska. Then members of Historian recently moved east to try out the Rapid City, S.D., music scene. It’s closer to major cities than their old state. The four-piece met in Alaska and formed their indie rock act three and a half years ago. The name? It’s not because any of the band members are history buffs. They wanted something that had a lot of depth to it. This is the first time the band will hit the road on a Northwest tour, stopping at Mootsy’s on Friday to promote their seven-track summer release Romance. Check out their set and let their sultry, harmonious sounds wash over you.
