Best known to Provincetown audiences for her appearances in CLASSICAL VARLA, and the world premiere of MAD SCENE by Jeffery Roberson, Montalvo returns to Provincetown for one night only.

Montalvo made her Carnegie Hall debut under the baton of Christoph Eschenbach with the Philadelphia Orchestra. She was most recently invited by him to perform the role of Sophie in Der Rosenkavalier opposite Renee Fleming with the National Symphony Orchestra at the Kennedy Center in Washington, DC. Recent engagements include Knoxville: Summer of 1915 last season at the Ravinia Festival in Chicago. Montalvo will return to the Salzburg Festival for concerts in the summer of 2019.

As well as performing alongside many of the worlds most renowned conductors and orchestras, she has had the privilege of working closely with many of todays leading composers, including Matthias Pintscher, Olga Neuwirth, and Wolfgang Rihm. Several have written roles especially for her, including Peter Eötvos (Sierve Maria in Love and Other Demons), Pascal Dusapin (Prothoe in Penthesilea) and Marco Stroppa (Olbia in Il Re Orso). Her affinity for contemporary music has led to regular engagements with ensembles including Klangforum Wien, Ensemble Intercontemporain, International Contemporary Ensemble (ICE), Ensemble Remix and Ensemble Modern.

Although she has achieved success in a wide range of operatic repertoire, Montalvo is particularly associated with the title role of Bergs Lulu. Following her debut in the part at the Opéra National de Paris, Le Monde described her performance as a true revelation: The American soprano possesses real stage and vocal presence, and executes the exhausting role with incredible intensity. Subsequently, Lulu has become the centerpiece of her stage work; she has performed it at houses including Deutsche Oper Berlin, Théâtre du Capitole Toulouse, Teatro de la Maestranza, Theater an der Wien, Komische Oper Berlin, and at Theater Basel, in the acclaimed production by Calixto Bieto.

Outside the opera house, Montalvo has a particularly close working relationship with Christoph Eschenbach, who has been both a mentor and a regular concert partner throughout her career. Since conducting her Carnegie Hall debut with the Philadelphia Orchestra, he has invited her to work with him alongside orchestras including the Vienna Philharmonic, the Houston Symphony, the London Philharmonic, the Munich Philharmonic and the Orchestre de Paris.

She has also worked with conductors including Daniel Harding, Vladimir Jurowski, Christopher Hogwood, Yuri Temirkanov, Bernhard Kontarsky, Sylvain Camberling, Sussana Mälkki, Lothar Zagrosek, and Sir Neville Marriner, and with orchestras including the Cleveland Orchestra, the Los Angeles Philharmonic, the San Francisco Symphony, St Petersburg Philharmonic, DSO Berlin, SWR Sinfonie-Orchestra, RSO Wien, Finnish Radio Symphony Orchestra, and the Bamberger Symphoniker. She has performed at houses including Opernhaus Zürich, Bregenzer Festspiele, Gran Teatro del Liceu, Baden-Baden Festspielhaus, Teatro Real de Madrid, Glyndebourne Festival Opera, Theatre du Chatelet, Théatre de Geneva, La Monnaie de Munt, Opera de Monte Carlo, Lithuania National Opera, Polish National Opera and Opera Comique.
