On 22 January 1785, Mozart's father Leopold wrote from Salzburg to his daughter Nannerl, retailing the news "that last Saturday (Wolfgang) performed his six quartets [in truth probably just KV 387, 421 and 428] for his dear friend Haydn and other good friends, and that he has sold them to Artaria for a hundred ducats."

The final four works of the set are recorded here by leading members of the Vienna Philharmonic. The Musikverein Quartet, first came together in 1973 as the Küchl Quartet and made their Decca recording début at the Sofiensaal in December 1975 with Mozart's KV 499 and KV 589. Led by the then junior VPO concertmaster Rainer Küchl (born 1950), the group was soon given the Barylli Quartet's old title of Wiener Musikverein Quartett, which it holds to this day.

Both, KV 428 and KV 464 receive their first international release on CD.
