Tegan and Sara rocked the stage of ‘Jimmy Kimmel Live’ last night (Jan. 31) with a performance of their single ‘Closer,’ and they certainly didn’t disappoint with their passionate delivery of the catchy tune.

The track appears on the Canadian duo’s latest studio release, ‘Heartthrob,’ which dropped on Jan. 29 via Warner Bros. Click here to find out what Diffuser.fm thinks of the new record.

The Quin twins shed some light on the song in an interview with Rolling Stone last fall. "In short, I was writing about my youth,” explained Tegan. “…a time when we got closer by linking arms and walking down our school hallway, or talked all night on the telephone about every thought or experience we'd ever had. It wasn't necessarily even about hooking up or admitting your feelings back then. In fact, that rarely happened. It was the anticipation of something maybe happening that was truly exciting and satisfying. We were perpetually getting closer, yet we rarely got physical with one another, if ever.”

“These relationships existed in a state of sexual and physical ambiguity," she added. "Is there anything more romantic than that?"

Although they were forced to cancel a few recent shows due to illness, Tegan and Sara have resumed their tour in support of the new record – here's the itinerary.
