From classics to contemporary, the Islands a Cappella choir will ring in the holiday season with performances on Orcas, Lopez and San Juan islands, beginning Friday, at 6 p.m., at Rosario Resort.

Directed by Angel Michaels and featuring singers from Orcas, Lopez and San Juan, the choir will perform Saturday on Lopez, at Lopez Center for the Performing Arts, at 6 p.m. , and then Sunday at San Juan’s St. David’s Episcopal Church, beginning at 6 p.m.

At each venue, the program spans the millennia, with songs by Michael Praetorius and by Heinrich Isaac, “A Virgin Shall Conceive”, from the 16th century, through Maurice DuRufle’s “Where There is Love” from the 20th century, to songs by contemporary composers, such as Damien Mocnik of Orcas, “Verbum Supernum”; and Morten Lauridsen, who lives in Los Angeles and on San Juan Island.

The choir will also perform a variety of familiar Christmas-time tunes, such as “What Cheer”, “Deck the Halls” (spiced by a fascinating rhythm in 7/8 time), and a modern spiritual, “Jesus is Born in Bethlehem,” featuring tenor solo Gary Alexander. The show also includes several audience-participation songs as well, including “Away in a Manger”.

Tickets can be purchased at the door for the performance at St. David’s, 760 Park Street; $10 adults, admission for those 18 and under is free.
