The singers from Boston-based choral ensemble Blue Heron come to town with a program of Advent and Christmas songs from fifteenth-century England. Accompanied only by harp, the ten voices will perform holiday hits including “Ther is no rose of swych vertu,” “Nowel: Owt of your slepe aryse,” and “Ave rex angelorum.” Fun! This sort of performance allows you to feel like you’re being Christmassy without having to endure a lot of forced cheer, which is nice.
