The following is from the March 2004 Encore, publication of BMG, describing the Art of Fugue: "The world-renowned Emerson String Quartet memorably interprets Bach's enigmatic final masterpiece -- even though the string quartet as a form was unknown to Bach." Okay, Listfolk: What was the first string quartet? This is a request for information, not a trivia question. BTW, this disc is on sale at BMG for $4.99. Mitch Friedfeld
