I listened to this music yesterday, and I was thrilled. It was performed by the Escher Quartet. In particular, I kept going back to the second movement, the warm and lyrical Andante.
The String Quartet No. 23 in F major, K. 590, was written in June 1790 by Wolfgang Amadeus Mozart. It is the third of the so-called “Prussian Quartets”.
There are four movements:
Allegro moderato, in F major
Andante, in C major
Menuetto: Allegretto
Allegro, in F major
The quartet was written for and dedicated to the King of Prussia, Friedrich Wilhelm II, an amateur cellist. It is written in a similar style to the quartets of Joseph Haydn. Mozart and his friend Karl Lichnowsky met the king in Potsdam in April 1789. Mozart played before the king in Berlin on 26 May of that year.
Here is the wonderful second movement from this composition:
