"No one will confuse this with any of our other records," Sara explained upon the release of 2013's Heartthrob. "It's got a bigger, bolder, happier sound." And Tegan was explicit about the supersized ambitions motivating the record. "I kept asking myself: Can I hear this in an arena? Can I hear this on a teenager's iPod as they're riding the bus to school?" Heartthrob doesn't just sound different, it represents a more collaborative way of making music. For the first time, the sibling duo actually wrote a lot of the songs together (in the past there were Tegan songs and Sara songs), and they surrendered more control than usual in the studio, dividing songs between a trio of producers (Greg Kurstin, Justin Meldal-Johnsen, and Mike Elizondo) and a handful of outside musicians to capture the sound they were looking for. Climbing to No. 3 on the US Billboard 200 and topping the US Top Rock Albums chart, Hearthrob earned a 2013 Polaris Music Prize nomination and took home the Juno Award for Pop Album of the Year and Juno Award for Single of the Year for "Closer."
