The country duo Granville Automatic performs songs from An Army Without Music, a recording project in which each song is inspired by a Civil War battle. And since they are appearing on the 150th anniversary of the Battle of Chickamauga, Vanessa Denae Olivarez and Elizabeth Elkins will debut their new song about that confrontation.

Olivarez was in the Top 12 of the 2003 season of American Idol and starred in the Canadian stage production of Hairspray. Elkins was a grand prize winner in the John Lennon Songwriting Contest. Together they have released the albums Granville Automatic and Live from Sun Studio.
