The twin sisters from Canada depart from their indie singer-songwriter roots with their latest album. The music on Heartthrob is often loaded with a carefully articulated sense of doubt that Tegan and Sara suggest needs to be shaken off through a triumph of the pop-music will.

The icon's new album plays like a collection of discreet singles, with each performed in a different style, genre and mood. In this way, the album isn't a return to form, in part because David Bowie never took one form to begin with.

Recruiting the likes of Guy Clark and Vince Gill, the country singer and member of The Pistol Annies works within a tradition that extends back well beyond her twentysomething years. Monroe avoids the pitfalls of cliche, with sentiments on her new album that are nothing if not nicely ambivalent.
