"I think it's fun to have fans that are our age because we're not home a ton and we don't get to see our friends all the time," Sydney, the band's 16-year-old lead singer, told Radio.com. "I like to think I'm making a couple of hundred friends every night. And after the show we get to have these conversations with these kids our own age and for some reason because we're musicians and close to their age they feel a certain openness with us. I don't really understand why, but it's really cool."

This past summer Echosmith held a spot on the Warped Tour, where they were exposed to a much different crowd than they were used to. "It's a very eclectic tour�we wouldn't have been a natural pick," Jamie, the guitarist and eldest in the family, explained. "At first we were a little hesitant, but we said, 'Let's do it, but let's see if anyone will like us.'"

People did and many of those new fans starting coming up to the band after shows to chat about their music. Most often they talked about "Cool Kids," a dreamy song off their 2013 debut, Talking Dreams, that tells the story of a boy and girl who just want to be noticed, hinging on the lines: "I wish that I could be like the cool kids/'Cause all the cool kids, they seem to fit in."

Jamie says the message of the song is simple: the coolest thing you can be is yourself. But more often than not, fans tell the band that they relate to the kids they're singing about. That they feel like the outsider looking in.

"This cry to be like the cool kids� it's something that everyone kind of goes through whether you want to act like it or not," Jamie said. "There's always somebody out there that you kind of wish, 'If only I could do this, or do that.' I think that's why it connects with people so well."
