Debuting at the 1969 Marlboro Festival, the Cleveland Quartet, a group of talented young American musicians, earned immediate acclaim as an outstanding chamber ensemble. Over the next 25 years, they delivered performances worldwide, including nearly 30 complete Beethoven cycles in the US and Europe. Pioneers as classical artists on televised Grammy awards, their exclusive label from 1972 to 1987 was RCA Victor. Stereo Review hailed their Beethoven recordings as a 'quartet in the great tradition.' Sony Classical now proudly presents their entire, critically acclaimed discography in a 23-disc box set.
