The Greencards are an acoustic phenomenon who have toured with Bob Dylan and Willie Nelson, Rosanne Cash, Kasey Chambers, Robert Earl Keen, and more. They're one of the most tested, versatile, and mesmerizing live acts on the road today and took Best New Band at the Austin Music Awards in 2004. Although they create some of the finest Americana around, they're not American. The band consists of one Englishman and two Australians. "Viridian" bridges the gap between traditional bluegrass, newgrass, and the jamband world.
