Video Meet Rolling Stone's New Breaking Artist, the Pierces

Who: Two preternaturally gorgeous Southern sisters who deliver sassy lyrics and traditional harmonies.

Hear It: Check out the Pierces MySpace page and go buy their new album Thirteen Tales of Love and Revenge, in stores now.

Watch it: Learn to make margaritas with Catherine and Allison Pierce, the kind of girls who love dancing to the perfectly cheesy Kenny Rogers/Dolly Parton hit "Islands in the Stream."
