The Dixie Chicks are an American country music trio. Sisters Emily Robison and Martie Maguire (n-e Erwin) started the group with Robin Lynn Macy and Laura Lynch in 1989 in Dallas, Texas. Macy left the group in 1992, while Lynch was replaced with Natalie Maines in 1995. They are currently the highest-selling female musical group in history, according to RIAA Gold & Platinum album certifications. The group aroused considerable controversy for publicly denouncing President George W. Bush and the imminent invasion of Iraq during the European leg of their Top of the World tour supporting Home. Many country music stations immediately pulled their music from the air, and the band received criticism from many corners of the media.
