Some of the most familiar names in country music have flocked to Audium Entertainment, the label established late last year by industry vets Nick Hunter and Simon Renshaw. The roster now includes Loretta Lynn, Ricky Van Shelton, Billy Swan, Daryle Singletary, the Tractors and the Kentucky Headhunters. Swan’s new album, Like Elvis Used To Do!, will be out Tuesday. Shelton’s Fried Green Tomatoes is slotted for May 23. Audium also will repackage and distribute recordings originally released by the Country Music Foundation. Audium is distributed by Koch International. The label will have its own Fan Fair show at 1 p.m. on June 15. So far, Lynn, Shelton and Singletary have been booked.
