The Mount Airy Museum of Regional History, in cooperation with the North Carolina Humanities Council, continues its exploration of the area’s musical heritage as it hosts the local showing of “New Harmonies: Celebrating American Roots Music,” a Smithsonian Institution traveling exhibition.

On Wednesday, at noon, bring a lunch and join Chester and Nick McMillian of Back-Step for a “Lunch and Learn” at the Museum Annex, 144 W. Oak St. This program is free and open to the public.

Eighth-generation Round Peak musician Nick McMillian has a combination of a deeply rooted traditional style and his own infectious fiddling sound, haunted by the legendary Round Peakers he knew so well as a child. Chester McMillian, Nick’s father, played with Tommy Jarrell both at home and in venues all across the country. Tommy favored Chester’s innovative style of guitar picking, and he recorded the albums “Picking on Tommy’s Porch” and “Joke on the Puppy” with Chester.

New Harmonies will be on view through April 24. Mount Airy Museum of Regional History and the surrounding community was expressly chosen by the North Carolina Humanities Council to host “New Harmonies: Celebrating American Roots Music” as part of the Museum on Main Street project — a national/state/local partnership to bring exhibitions and programs to rural cultural organizations.
