No clue what instrument Basia Bulat is playing here. As a commenter sort-of notes, it looks like a combination of a hammered dulcimer and auto harp. I have never seen anything like it before.
What a voice, too.
Too much drums in this mix, but also what a great song:
youtube is not running so well for me tonight, but npr identifies the instrument as a pianoette.
