At first glance, the coming together of a string quartet and a guitar duo may seem like nothing more than an entertaining night on the town. But these two super-groups of the string world, both having irrevocably altered the face of their respective traditions, have something altogether different in mind.

Think around the world in one evening of wild celebration, astounding virtuosity and deep beauty, from the lands of Africa and India to the Appalachian Mountains, to the rhythmic poetry of the Balkans, the warmth and passion of Brazil, the hard-swinging elegance of Gypsy jazz a la Django Reinhardt and Stephane Grappelli, and everything in between. Join the Assad Brothers and the Turtle Island Quartet as they postulate a new unified string theory of their own design.
