But be careful about calling them "indie": while they have the D.I.Y. ethic of indie rock in its purest sense, they don't really relate with the scene of the past decade and a half or so.

"We're very human, and we're fun," Johnson says. "We're excited to be doing what we're doing. There is an era of indie music where it just because just about trying to look cool on stage. That 'bored' look became a thing. On stage you can see we're enjoying ourselves, because we are enjoying ourselves. And we want to show it."

He continues: "If you come from a pissed off place, be pissed off. If you're coming from a sad place, be sad. But just don't be bored. Watching people be bored, or look bored, is boring to watch. Seeing her," he says, pointing at Kim, "She will be dancing and smiling at any given moment in her life."

Dancing, and in particular, Kim's dancing, is an important visual aspect of the group, and distinguishes them from the duller indie rock acts. "To see a member of an indie band dance like that in a video, people are like, 'Whoa! Kim! You've got moves!' She's very comfortable with her body." In fact, both Kim and Matt are pretty comfortable with their bodies, which has always been a calling card of sorts for the duo.

Kim's dancing, and a bit of Matt's is on display in the video for "Hey Now," from New Glow, which sees her tearing it up at a waterfront park in Brooklyn. As Kim says, "So, I like to dance, and when you come to our shows, it happens. Matt was just like, 'Why don't we just have a video where you dance?' We have a video like that for 'Overexposed' from 2012's Lightning. But doing it outside was maybe a bad idea. In New York City in February! Not the first time we did that!"

In fact, their breakthrough came via a rather frigid music video: "There's a little song called 'Lessons Learned,'" Matt says, "Where we got naked in Times Square."

Kim laughs, "You think we would have learned by now!"
