The Greencards

From Lastfm:

The Greencards are a bluegrass music band from Austin, Texas, that formed in 2003. The band is composed of two Australians-Kym Warner (mandolin) and Carol Young (bass)-and Tyler Andal of White House, TN (fiddle).

According to the band, their music is described as "high energy acoustic music". They have to date released one independent album and two albums through Dualtone, a Nashville label. Their music has been called Celtic-influenced and bluegrass-flavored, but they have a distinctly American sound despite their overseas origins. The band has been nominated in the Americana Music Association Awards for 2006 in the category of New/Emerging Artist of the Year. In 2005, they toured extensively with Bob Dylan and Willie Nelson.

In 2004, the Austin Music Awards named them Best New Band. In 2005, Country Music Television named their album Weather and Water one of the ten favorite bluegrass albums of the year, saying, "At the nexus of bluegrass, country and pop, this charming trio immediately win over such diverse audiences in concert. Luckily, their winning personality translates to this disc-even with several melancholy, yet melodic, songs. Not for nothing did Bob Dylan and Willie Nelson choose them to open their summer tour of minor league ballparks."

From Wikipedia:

The Greencards are a progressive bluegrass band that formed in Austin, Texas, and are currently based in Nashville, Tennessee. The band was founded in 2003 in Texas by Eamon McLoughlin, an Englishman, and Australians Kym Warner and Carol Young. The musicians originally performed in local Austin bars, and soon found increasing acclaim. They have released one independent album, Movin' On, in 2003, and two albums, Weather and Water, and Viridian, on the Dualtone record label. Their fourth album, Fascination, was released on Sugar Hill in 2009.

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 the Billboard magazine's Bluegrass Music Chart, making The Greencards the first international band to ever 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 for a Grammy Award at the 50th Grammy Awards.

The Greencards are noted for their playing of American bluegrass with a worldly feel, and for their incorporation of other genres of music. Often labeled as part of, and said to be representative of, the "newgrass" movement, they draw from Irish folk music, gypsy music, rock 'n' roll, folk balladry, and Latin American musical sources. The Greencards' sound has been compared to progressive American folk rock, and they have been credited with helping to expand bluegrass music.

Eamon McLoughlin left the band in December 2009, and currently resides in Nashville TN. He was replaced by Tyler Andal, a talented 21 year old fiddle player from White House, TN.
