WORTHINGTON - Violinist Karla Colahan and cellist Olivia Diercks, classically trained musicians from the Midwest who perform together as The OK factor, will perform at 7:30 p.m. Thursday at Memorial Auditorium Performing Arts Center.

The event is the second concert of the season for the Worthington Concert Association. Attendance is restricted to association members.

The OK Factor plays a number of genres including bluegrass, jazz, pop and folk as well as original compositions. Their new-classical style has caught the attention of the Minnesota music community in which they live and work.
