A stellar lineup of artists, headed by Daniel Barenboim, comes together for the inaugural concert of the Pierre Boulez Saal, celebrating the idea of what this new hall stands for: to create a space where beloved classics, modern masterworks of the early 20th century, and music of our time can be heard side by side and inspire audiences and performers alike. Anna Prohaska and Jörg Widmann join Barenboim for Schubert’s lyrical scene Der Hirt auf dem Felsen, while Barenboim will also partner with the Boulez Ensemble’s strings in Mozart’s Piano Quartet. Karim Said and Michael Barenboim take on Berg’s Chamber Concerto, and Widmann will perform his Fantasy for Solo Clarinet. In tribute to Pierre Boulez, the program is bookended by his fanfare-like Initiale and sur Incises, for three pianos, three harps, and three percussionists.
