Beloved by performers, audiences, and composers alike, the piano quartet stands as one of chamber music’s most richly expressive forms. This program showcases landmark works from the Romantic era: Schumann’s pioneering contribution to the genre, Brahms’s passionate and expansive reimagining of its possibilities, and a rare early gem by Gustav Mahler—his only chamber work, a striking single-movement piece that reveals remarkable depth and intensity. Anchoring the concert are CMS’s longest-serving artistic directors, cellist David Finckel and pianist Wu Han, making a rare joint appearance on this tour.
