The Mystic Chorale is a local community choir of over 200 singers that celebrates the rich musical traditions of many cultures. On Saturday and Sunday, November 23rd and 24th, they team up with Arlington’s own Family Folk Chorale in a special concert entitled “Family.” We dropped in on a recent Mystic Chorale rehearsal and spoke with the choir directors, as well as some of the singers, to find out what they’re all about.
