Aubrey Atwater and Elwood Donnelly bring their unique stage performance to the New Moon Coffee House in Haverhill, Mass., on Saturday, Feb. 20, at 8 p.m.

This award-winning duo is known for their unique blend of traditional American and Celtic folk music and dance, along with original songs and poetry.

Prior to the main act, the evening starts with an opening set by Goli.

Aubrey Atwater and Elwood Donnelly are the energetic husband-and-wife team known as Atwater-Donnelly.

They blend vocals with an array of instruments, including the mountain dulcimer, old-time banjo, tin whistle, guitar, limberjack, mandolin, harmonica, feet and more.

Aubrey has been known to clog, play the banjo and sing at the same time. The two have traveled extensively for 22 years in the United States, as well as in Ireland, England, and Canada, to perform, as well as find their songs and dances. They have produced six books, a film, and 11 recordings that receive international airplay.

Goli is Vessela Stoyanova and Valerie Thompson on cello, marimba and voice. They describe themselves as a duo of misfit classical musicians with an appetite for world music. They perform a delightful and quirky collection of folk songs and modern chamber music.

The New Moon Coffeehouse is a nonprofit, all-volunteer organization dedicated to supporting and enjoying the creative talents of acoustic performers. Tickets to this performance are $20, available at the door starting at 6:30 p.m. Tickets may be reserved prior to the show by visiting www.newmooncoffeehouse.org, or by calling 978-459-5134.
