www.cmt.com biography The Dixie Chicks started out with sisters Martie (born Oct. 12, 1969) and Emily Erwin (born Aug. 16, 1972), who grew up attending bluegrass festivals and busking for spare change on Dallas street corners in 1989. With two additional women in the group, they were best known in Texas for drawing in country fans with their Western music and their colorful cowgirl outfits, and sold thousands of independently released albums. Ready for a stylistic change, they asked their lead singer to leave (the other member had already dropped out) and invited Natalie Maines (born Oct. 14, 1974) to join the band in 1995, replacing Laura Lynch.
