The Court Yard Hounds are a new group -- but they're hardly your typical baby act.
The duo is derived from one of music's best-selling bands -- the Dixie Chicks -- and their self-titled debut album is already among the spring's more anticipated releases.
Robison lives in San Antonio. Maguire lives in Austin.
SXSW will mark the first time they will be center stage since the Dixie Chicks took-off more than a decade ago, when it was Lubbock's Natalie Maines singing lead.
Many country stations quit playing the Chicks in 2003 after Maines told a London audience, about then-President George W. Bush: "Just so you know, we're ashamed the president of the United States is from Texas."
Almost overnight, Maines became a lightning rod in the debate over the Iraq war.
