The Keller Quartet—named for its founder, the violinist András Keller—rose to international prominence in the 1990s when they won the Évian and Borciani competitions. Made up of solo artists passionate about chamber music, the Keller Quartet is animated by a spirit of boundless curiosity that leads them to a great variety of repertoire, from Bach to Bartok and everywhere in between. In 1994, the ensemble turned their focus to the work of Brahms, performing the full set of the composer's string quartets in Munich.

The third and final quartet, Op. 67 in B-flat major, marks a departure from the two earlier quartets right from the introduction, which calls to mind the sound of a trumpet fanfare. This work's more lighthearted, even pastoral character closes the complete cycle of Brahms's quartets on a joyful note.
