Taking its name from Mozart's 'Dissonance' Quartet, this witty, buoyant and ultimately moving play follows the Bradley Quartet as they arrive in New York for a concert honoring their ten years together. Their fragile harmony implodes into a storm of jealousies and frustrations when Beth, the cellist, agrees to give music lessons to one of America's biggest rock stars, and their egos, loyalty and love are all put to the test.
