I was invited to a Pentatonix concert by a friend who had free tickets to see them a couple of weeks ago. None of us knew their music though I had heard of them, and it was a nice show. However, what caught my attention was one of their opening acts, Echosmith.
They performed a so-far unreleased song called
Diamonds In A Sea Of Pearls, here are two videos of them performing it in different locations. I really hope they release it on their next album.
