Tegan and Sara "Closer" (live on 'Letterman')

Tegan and Sara 'Closer' (live on 'Letterman')
Having just announced the details of the upcoming Heartthrob, indie rock twins Tegan and Sara stopped by The Late Show With David Letterman last night (November 20) to perform their new single "Closer."

The Quin sisters don leather jackets and leave their guitars at home for this pulsing, club-friendly synth track. They harmonize tightly and plink away on a keyboard, making for a much more energetic performance than we're used to seeing on late night TV. The clip ends with the host asking the sisters which one is Tegan and which one is Sara.

Heartthrob is out January 29 on Warner Bros. Records. Learn more details here.
