The string quartets of Beethoven are among the greatest works of their kind, but he composed other works for quartet which have been neglected. This album is dedicated to these intriguing rarities. Alongside the wild and monumental Grosse Fuge, in many ways the culmination of Beethoven's achievements in the string quartet genre, this recording further displays his mastery of counterpoint by bringing to light brilliant yet forgotten original versions of his quartets Op. 18, No. 1 and Op. 131, plus six virtually unknown miniatures, including his Preludes and Fugues.
