Josie Dunne belts out of the side of her mouth, strumming intricate jazz progressions and overwhelming the small stage at Rockwood Music Hall.

Her band isn't there. It isn't even really a concert, but rather a showcase, mostly designed to impress record label executives and members of the press. Josie doesn't care. She casually talks between songs and laughs through her set, giving one the impression that she would perform exactly the same whether she's singing for ten people or ten thousand.

She may be young and inexperienced, but it's easy to pick out that shimmering clarity–the one that all great pop artists have–in her voice. And, even as a novice performer, Dunne has managed to tap into a level of authenticity most veteran musicians never find. On June 1st, she released her debut EP titled To Be The Little Fish, and the songs on it have garnered more than 1.5 million hits on Spotify to date. We decided to give her call before she gets too famous to talk to us.
