In its 12th year, Mysteries of Christmas has become a traditional part of the Advent season for many in the Loras and Dubuque communities. This year’s performance, Angels Long to Look, will be held on December 2 at 7:30 p.m. at Dubuque’s Church of the Nativity on Alta Vista Street. The joyous 90-minute performance will feature vocal and instrumental pieces integrated with prayers and spiritual messages to enter more deeply into the Advent season. The admission offering is $8 per person or $20 for a family four-pack. Online purchasing will be available in November.
