In the early 1960s, four young musicians who had been playing chamber music at Rudolf Serkin’s Marlboro School and Festival in Vermont were encouraged to form a string quartet. In July 1964, the Guarneri Quartet gave its first concert and less than a year later made its first recordings under contract to RCA Victor. For the next 45 years, with only one change of personnel, the Guarneris performed all over the world and amassed a large, wide-ranging, prize-winning discography. Sony Classical now presents, for the first time in a single collection, all the recordings made by the Guarneri Quartet for RCA between 1965 and 2005.

When the announcement came of its retirement at the end of the 2008–09 season, the eminent British critic Rob Cowan wrote a perceptive, affectionate tribute to the Guarneri Quartet in Gramophone, comparing it to the Juilliard Quartet, the other superb ensemble that had dominated the American quartet catalogue for so many years. Using their respective Bartók recordings as an example, he contrasted the “cut-glass precision” of the Juilliard’s early-60s set to the Guarneri’s “volatile, free-spirited, generously expressive and tonally rich” performing style in its RCA cycle from the mid-70s.
