Caitlin Cary & Thad Cockrell: Begonias

Traditional country music is marriage music, and there's no better way to dissect a troubled marriage than to have a female country singer and a male country singer trade lines in a duet. Caitlin Cary and Thad Cockrell are not married to each other, but they understand the institution's vicissitudes so well that they have co-written nine terrific songs for their first duo album, Begonias, and provide spirited, back-and-forth vocals.
