Talking to Glamour, Tegan said she'd been listening to a lot of Kate Bush, Katy Perry and Britney Spears ("I loved her last record, by the way") when making the forthcoming 'Heartthrob', while Sara was enjoying some Alicia Keys.
Tegan also added: "I think 'Heartthrob' is a return to us harmonizing melodies together, which is a throwback to quintessential Tegan and Sara. But it's also a brand new vibe for us. It's supercharged."
'Brand new vibe'.
They also shared the Greg Kurstin-produced 'I Was A Fool', which sounds a lot like this.
