Northfield, the vocal ensemble based in Farmington, will perform at 7 p.m. Saturday, Dec. 9, at the Skowhegan Federated Church, 13 Island Ave. in Skowhegan, and at 3 p.m. Sunday, Dec. 10, at Nordica Auditorium at UMF’s Merrill Hall in Farmington.

The music, sung in an a cappella style, will include some holiday music, as well as an eclectic mix of sacred, secular and silly songs. In addition to their usual selections from the Early American shape note tradition, Northfield will perform pieces from the European Renaissance, Late Romantic and Impressionist period, and several special new-to-their-repertoire, twentieth and twenty-first century selections.

Opening the concert in Farmington will be the University of Farmington’s premier a cappella group, the Clefnotes. This performance is supported by the ArtsFarmington organization, which promotes and sponsors a wide variety of arts events in the greater Farmington area.

Admission for these performances is by donation. For more information, visit northfieldsingers.wordpress.com/ or call 778-5074.
