Their debut album, "Movin' On", was the recipient of local Texas awards and charted on Americana radio stations. Country Music Television named their follow-up "Weather and Water" as one of the ten best bluegrass albums of 2005, and The Greencards were invited to tour with Bob Dylan and Willie Nelson in the same year. "Viridian" would go on to take the number one position on "Billboard" magazine's Bluegrass Music Chart, making the Greencards the first international band to do so. "Viridian" was a critically praised album, and was nominated for Best Country Album by the Australian Recording Industry Association. The track "Mucky the Duck" from "Viridian" was nominated as the Best Country Instrumental Performance at the 50th Grammy Awards.
