The german bass-baritone Hanno Müller-Brachmann was musically educated at an early age in the Knabenkantorei Basel. He studied with Ingeborg Most in Freiburg, with Rudolf Piernay in Mannheim and attended the Lied class of Dietrich Fischer-Dieskau in Berlin.

While still a student, Daniel Barenboim brought the 27-year-old three-time competition winner to the Berlin State Opera Unter den Linden, where he was a member of the ensemble for 13 years. Here Hanno Müller-Brachmann embodied the great Mozart roles in his field, and was also heard as Kaspar (Der Freischütz), Amfortas (Parsifal), Escamillo (Carmen), Banquo (Macbeth), Goulaud (Pelléas et Mélisande) and the Count (Der ferne Klang), as well as in the world premieres of Elliott Carter's What next? and Pascal Dusapin's Faustus, the last night. In addition to Daniel Barenboim, important partners for him on the podium in Berlin have included Michael Gielen, René Jacobs, Sebastian Weigle, Gustavo Dudamel, Pierre Boulez, Sir Simon Rattle and Philippe Jordan.
Guest appearances have also taken Hanno Müller-Brachmann to the State Operas in Hamburg, Vienna and Munich, to the Theater an der Wien and to San Francisco. The recording of Mozart's Die Zauberflöte in Modena under the baton of Claudio Abbado with Hanno Müller-Brachmann in the role of Papageno was released by Deutsche Grammophon and received a Gramophone Award as Opera Recording of the Year. In Cleveland he sang Golaud in Debussy's Pelléas et Mélisande and the Music Teacher in Ariadne auf Naxos under the baton of Franz Welser-Möst. His most influential directors were Harry Kupfer, Peter Mussbach, Martin Kusej, Doris Dörrie, Keith Warner and Peter Sellars.

As a concert singer, the bass-baritone experienced unforgettable moments in performances with Adam Fischer, Daniel Harding, Gianandrea Noseda, Andris Nelsons, Vladimir Jurowski, Kirill Petrenko and Lorin Maazel. He has worked with Bernhard Haitink for many years, for example with the Chicago Symphony Orchestra, the Concertgebouw Orchestra Amsterdam, the Orchestra of La Scala in Milan and the Bavarian Radio Symphony Orchestra. With this orchestra, conducted by Mariss Jansons, he sang the world premiere of Wolfgang Rihm's Requiem-Strophen in 2017.

Outstanding recent performances include orchestral songs by Hugo Wolf with the BR Symphony Orchestra under Iván Fischer in Munich, Anton Webern's Cantata No. 2 with the Ensemble Intercontemporain under the baton of Matthias Pintscher and Dvorak's Stabat mater with the Orchestre National de France under Christoph Eschenbach in Paris.
