From the castle of Rammenau, the Gewandhaus-Quartett plays Eine kleine Nachtmusik, K. 525 (Serenade 13 for Strings in G major) by Mozart. This serenade was completed in Vienna on August 10, 1787, while Mozart was working on the second act of the opera Don Giovanni, and was not published until about 1827, long after the composer's death. The traditionally used name of the work - A Little Night Music - comes from notes in Mozart's personal catalog. Founded in 1808, the Gewandhaus-Quartett is the oldest quartet in the world, continuously performing for more than 200 years. It is composed of members of the Gewandhausorchester Leipzig and has had more than 200 musicians to date. The Gewandhaus-Quartett is currently composed of Frank Michael Erben (first violin), Conrad Suske (second violin), Volker Metz (viola), Jürnjakob Timm (cello), and Steffen Adelmann (double bass).
