When it comes to combining the golden harmonies of country music with the slick edge of pop, The Chicks (formerly known as Dixie Chicks) have learned from the best. The band's folk-rock introspection channels the bewitching ballads of Stevie Nicks and Alison Krauss, while their bluegrass chops nod to the hot licks and upbeat shuffle of New Grass Revival, and their twangier tendencies pay respects to the swaggering outlaw-country legend himself, Waylon Jennings.
