Southern Ohio Indoor Music Festival

The Southern Ohio Indoor Music Festival is a two-day bluegrass festival presented twice a year in March and November at the Roberts Centre near Wilmington, at the intersection of US 68 and Interstate 71. It is a successor to the bluegrass concerts that Joe Mullins promoted at Xenia High School and Fairborn High School, and those that his dad Paul Mullins presented at Conover Hall in Franklin and other venues.
