Country music icon Marty Stuart has launched a new imprint, Superlatone Records, whose first release will be the gospel collection Soul's Chapel, due August 30.

The album was produced by Stuart and includes a guest appearance from Mavis Staples. Universal South, the Nashville-based arm of Universal Music Group, will distribute.

Superlatone is being described as a home for music and cultural offerings from the prolific Stuart and a vessel for his interest in southern culture.

Other upcoming releases are Marty Stuart & His Fabulous Superlatives Live at the Ryman and Badlands.

The first is a bluegrass concert Stuart and his band recorded at the Ryman Auditorium in Nashville in 2003. The latter is a themed record about the historic and contemporary lives of Native Americans. Produced by Stuart and John Carter Cash, the collection includes one obscure song written by Cash's father, Johnny Cash, who was also Stuart's father-in-law at one stage. Stuart's current wife, Connie Smith, makes a guest appearance.

Stuart, a country music historian and songwriter, most recently recorded for Columbia Records, where he did two tours of duty interrupted by a long stint at MCA Nashville in the '90s.

In addition to these recordings, Stuart is working on six books, including three collections of his photography.
