The clarinet sonatas mark the end of Brahms’s output of chamber music and perhaps its peak. Their gentleness and tenderness combine gracefully with the twilight glow that emanates from these pieces, showing a disarming simplicity close to Mozart. The Horn Trio, on the other hand, expresses the ardor and energy of a composer in his early thirties and at the height of his artistic powers. Geoffroy Couteau moves with sovereign ease from one mood to another in these works, bringing out their vividly contrasting colors and emotions in perfect unison with his attentive partners.
