SINGAPORE — Echosmith is now one of this year’s biggest breakout acts after their single Cool Kids became a hit worldwide, hitting Top 10 charts around the globe and accumulating more than 45 million views on YouTube alone.

So it’s hard to remember that the Sierota siblings really are just kids themselves. Aside from big brother and guitarist Jamie Sierota, who is 22, the rest of Echosmith is made up of teenagers, including 18-year-old lead singer Sydney Sierota, 19-year-old bassist Noah Sierota and drummer Graham Sierota, who is 16.

Their youth and the song’s irresistibly catchy beat may be the reason why teenagers — and even adults — have fallen in love with Cool Kids. And it doesn’t hurt that the Los Angeles indie-pop band knows exactly what it means to grow up feeling just slightly uncomfortable in their own skin.

“Certainly when you’re growing up, you do little things to try to be cool,” said Noah in a phone interview with TODAY. “Like when you try to pretend you’re not yourself, to change the way you talk, compared to other people. You try to sound like a Californian surfer or something, when you’ve never surfed in your life. I think a lot of people do that especially when they are young — how they joke, or the silly words they say.”

He added: “It’s just trying to fit in, to be cool, maybe even sometimes to be different — to talk the way people don’t necessarily talk.”

But thanks to Cool Kids, Echosmith never has to try any more. Noah, for example, now gets attention from acquaintances who didn’t think he was quite so cool before the song hit the charts.

“I think when you have a successful song, you get lots of messages on Facebook and text messages from people you didn’t know very well, or didn’t talk to you before, pretending to be your best friend,” he quipped. “It’s bound to happen. I’m kind of used to it.”

One more attractive consequence of writing and releasing a hit song, however, is the opportunity to travel the world. Over the last year, Echosmith has been to countless cities in Europe and America to hold their own concerts as well as, on occasion, perform with acts such as Taylor Swift, Owl City, Young The Giant and American Authors. The band is set to make a stop in Singapore in August.

“It’s like a dream for us, to be able to travel and meet different people who speak different languages, but who were able to sing our music,” Noah said, adding that touring with Sydney, Jamie and Graham sometimes feels like a “family road trip”, with laughter over music and arguments about “which restaurants we all want to eat at”.

Noah says the band doesn’t have an exact date for their next album yet, but hope to return to the recording studio next year. “I think the biggest challenge right now is to just pull through all the different time changes we are going through,” he said. “We are flying every single day, and I think right now we are trying to figure out how to keep our health going and stay alive; when we are travelling back and forth between Asia and Europe and America constantly.”

In the meantime, Sydney, Jamie, Noah and Graham just want to celebrate every little success that comes their way, before they figure out their next step.

“I think being able to enjoy the silly things, the joyful things and the simple things, whether things are going well or not, really helps you pull through anything,” he said. “Right now, we are having an amazing time touring the world, but there are still going to be times in my life where it doesn’t feel like, ‘Wow, incredible, I’m doing the most amazing things’.

“That is bound to happen, but it won’t feel so bad if I enjoyed the little things.”

Echosmith will perform in Singapore on Aug 11 at 8pm at The Coliseum, Hard Rock Hotel Singapore, Resorts World Sentosa. Tickets at S$78 (free standing) available at SISTIC.
