The tenor Martin Mitterrutzner, who hails from Hall in Tirol, received his training under Brigitte Fassbaender. He gained his first stage experience at the age of 10, performing as the First Boy in Mozart's The Magic Flute under Sir John Eliot Gardiner. Under the artistic direction of Brigitte Fassbaender, Martin Mitterrutzner began his career as a member of the ensemble at the Tiroler Landestheater. He later joined the ensemble of the Oper Frankfurt, where he built a broad repertoire, including roles such as Andres in Wozzeck, Giannetto in La gazza ladra, Iopas in Les Troyens, Fenton in Falstaff, and major Mozart roles like Belmonte, Tamino, Don Ottavio, and Ferrando. Since then, he has regularly returned as a guest to his former home theater and has appeared as Camille de Rosillon in a new production of The Merry Widow directed by Claus Guth, as well as Grimoaldo in Handel's Rodelinda, also directed by Claus Guth. In 2023, he once again made a role debut at the Oper Frankfurt, this time as Flamand in Richard Strauss's Capriccio.

Guest engagements have taken him to the Theater an der Wien (as Narraboth in Salome and Don Ottavio in Don Giovanni), the Festival Aix-en-Provence, the Zurich Opera House (as Tamino), the Salzburg Festival (as Brighella in Ariadne auf Naxos and Ferrando in Così fan tutte), the Bavarian State Opera (as Arbace in Idomeneo and Iopas in Les Troyens), and regularly to the Dresden Semperoper, where he has been heard in Mozart roles such as Tamino, Ferrando, and Belmonte, as well as in the role of Váňa Kudrjaš in Katja Kabanowa.

In the 2024/25 season, Martin Mitterrutzner will return to the stages of the Frankfurt and Hamburg Operas with a repertoire featuring works by Verdi and Mozart. Two other highlights include performances in the operettas Der Zigeunerbaron and Wiener Blut as part of the Johann Strauss Festival Year in Vienna, as well as a concert performance of Wozzeck under Alan Gilbert. He will also follow an invitation from the Qatar Symphony Orchestra to participate in their New Year's concert in Doha.

As a concert soloist, Martin Mitterrutzner possesses a wide-ranging repertoire, from Bach and Handel to works by Benjamin Britten and Sven David Sandström. He has performed with the Bamberg Symphony under Jakub Hrůša, the Choir and Symphony Orchestra of Bayerischer Rundfunk and the Hessian State Orchestra under Marc Piollet, the Montreal Symphony Orchestra under Kent Nagano, the Concentus Musicus, and the Cleveland Orchestra under Franz Welser-Möst. Recent engagements have brought him back to the Vienna Musikverein, and to the RIAS Chamber Choir Berlin.

On the song recital stage, the tenor regularly collaborates with pianist Gerold Huber, with whom he has performed at the Frankfurt Opera, the Cologne Philharmonie, the Heidelberg Spring Festival, and regularly at London’s Wigmore Hall and the Schubertiade Schwarzenberg. In 2021, he formed a song duo with renowned classical guitarist Martin Wesely, and their recording of Schubert's Die schöne Müllerin testifies to a close partnership.

Additionally, Martin Mitterrutzner can be heard on several CD recordings and DVD productions. For example, in 2015, the award-winning new recording of Vinci's opera Catone in Utica was released by Decca, conducted by Riccardo Minasi.
