“The OK Factor” will appear in worship services Oct. 8 at Christ Our Shepherd Lutheran Church in Peachtree City. Founded in 2012, the Minneapolis-based alternative-folk duo are Karla Dietmeyer Colahan, violin, and Olivia Hahn Dierks, cello. Much of their music is original. They have completed their fourth album together, which will be available in November. They have just completed a 6-month residency for Minnesota Public Radio as Class Notes Artists, and this week they will do a three-day residency at the College of St. Benedict at St. John’s University. They have performed throughout the Midwest in a variety of venues. They will play at 8:30, 10:50, and 11 a.m. on Oct. 8. Photo/Submitted,
