The Squirrel Butter duo performs traditional and original music influenced by Appalachian, early country, jug band and blues artists from the late 1800s through the 1950s. Charlie Beck plays fiddle, banjo and guitar, and Charmaine Slaven plays fiddle, guitar—and clogs while she sings. Their harmonies are infectious—and so is their energy.
7 p.m. at the Deception Pass State Park Amphitheater between West Beach and North Beach. Free.
