Toward the end of the season, the Boulez Ensemble once more explores a range of repertoire, from the 17th century to the present. Led by Antonello Manacorda for the first time, the musicians take on Monteverdi’s dramatic madrigal Combattimento di Tancredi e Clorinda and Schoenberg’s Ode to Napoleon Buonaparte, a musical plea against tyranny, written in 1942–43 in the composer’s American exile on a text by Lord Byron. The program concludes with two ensemble pieces by Luca Francesconi, whose works were heard in several concerts over the preceding months.
