Brahms String Sextet No.1 Op.18 in B flat.
Tchaikovsky: String Sextet Op.70 in D minor "Souvenir de Florence"
"The excellent Kocian Quartet joined by the no less excellent violist and cellist of the Prazak Quartet offer interpretations of an enthusiastic strength and of an exceptional stylistic correctness...perfect in the flight of the melody, in the airing of the counterpoint and of the polyphony, in rhythmical pulsation and in richness of tones." Patrick Szersnovicz - La Monde de la Musique. July 1988.
