Yo know what's weird? I'm having a hard time coming up with the "sounds like." Usually when I listen to a song it all comes to me instantly, but in this case, Came Power Club seem to have eluded me.
There's a hint of Oh Wonder, so let's start there, why don't we? It's probably rooted in the boy-girl vocal play.
Paperwhite? Nah, that's not it. Too mellow. But that's a good place to search from, because looking at artists similar to Paper White has uncovered acts like Two People, and this one totally overlaps with them.
Come to think of it, this reminds me a bit of Fihn, an act I added to my favorites about a week back. They've got a great sound, and the overlap here is certainly present.
Okay, I've worked through it, and I wrote it all down as I did so. Pretty cool, eh?
