The Conn Artists, a seven-member a cappella group, will perform a holiday concert on Sunday, Dec. 7, at 3 p.m. at Greenfield Hill Congregational Church, 1045 Old Academy Road. The Fairfield-based vocal group said it would sing both traditional carols and secular numbers.

A free-will donation of $10 is recommended, with 50 percent going to suppport the church's music program. Concert-goers may stay after the show for the lighting of the Christmas tree on the church grounds, the group said.
