Ireland’s Keith and Kristyn Getty arrive at Severance Hall tonight as they bring their fourth annual tour of Joy — An Irish Christmas to town. Thanks to some exposure on Public Television, the Gettys have become a household name. For tonight's performance, a crew of sharp instrumentalists will play Celtic, bluegrass, Americana and classical music. The concert begins at 7:30 p.m. and tickets start at $40. (Niesel)
