Building a base of real rock fans hit high gear when The Black Keys asked them to open a series of concert dates last October. "This is the thing, people that like licks, also like dance hits," joked Tegan in an interview. But according to Sara, rock's not the only genre they'd like to conquer. Although the duo recently collaborated with dance maven David Guetta, Sara said she'd even enjoy working with the masters of metal, Mastadon, proving the girls are truly up for anything.

Heartthrob marks the Canadian duo's seventh studio album. "Heartthrob really fit for me because I loved the concept. I idolize the people that I date," says Tegan to the Warner Sound. "I truly put them up on a pedestal and so it really resonated with me."
