The music of Robert Schumann has long been a major influence on Jörg Widmann’s own compositions. Joined by Sir András Schiff and Antoine Tamestit, he now brings three of Schumann’s works to the Pierre Boulez Saal that draw inspiration from poetic and non-musical ideas and reflect the Romantic fascination with the world of fairy tales. Alban Berg’s aphoristic Four Pieces of 1913 provide a striking contrast. The program concludes with Mozart’s “Kegelstatt” Trio, the historical model for the unusual combination of clarinet, viola, and piano.
