From the Rammenau Castle, the Gewandhaus-Quartett presents Mozart's String Quartet No. 21 in D major, K. 575. Nicknamed The Violet, this piece was composed in 1789 and is the first of the Prussian Quartets, a series of plays written for Friedrich Wilhelm II, King of Prussia and amateur cellist, in a style similar to Joseph Haydn's quartets. Founded in 1808, the Gewandhaus-Quartett is the oldest quartet in the world, continuously performing for more than 200 years. It is currently composed of Frank Michael Erben (first violin), Conrad Suske (second violin), Volker Metz (viola), Jürnjakob Timm (cello), and Steffen Adelmann (double bass).
