Take a whole lot of joy, pile another dab or so, then mix in a little more joy and you’d be starting to get the idea of what the David Wax Museum performance at the 9:30 Club last week was like.

Comprised of David Wax on a variety of stringed instruments and Suz Sleezak on fiddle and donkey jawbone (yes, you read that right) this group from Boston blends Mexican and American folk music into a sound that at it’s best is a veritable party for your ears. But there’s more to it than just the party. Their music is an exploration of Americana that is as utterly familiar as it is engaging and fresh in its delivery.

And oh that delivery.
