Country superstars The Mavericks, indie darling Conor Oberst and bluegrass legend Marty Stuart are among the performers announced for the seventh season of "Bluegrass Underground." 

"Bluegrass Underground" is a live music television show taped 333 feet underground in Cumberland Caverns. The natural caves—located about an hour from Chattanooga, near McMinnville, Tennessee—offer a unique listening experience.

Officials with the Emmy Award-winning show announced the full lineup today. 

Offering an eclectic mix of "bluegrass icons, rising stars of Americana, roots rock masters, country music game changers and Nashville gospel royalty," the new season promises to be the most varied to date.

Guests can purchase ticket packages for the weekend beginning Saturday at 10 a.m. A limited number of VIP weekend packages will be made available first, followed by general admission tickets at 11 a.m. 

The entire season will be taped March 24, 25 and 26 at Cumberland Cavern's Volcano Room.

According to a release from "Bluegrass Underground," fans can view multiple live concerts each day as the taping occurs. Each band will play a full set of music, much more than will appear in the half-hour TV show.
