Coming from a rich tradition, pianist Andreas Haefliger “belongs to that elite group of interpreters…one of the most serious, questing pianists on the circuit today… breathtaking virtuosity…a complete Beethovenian” (Telegraph, May 2018).

He has won many plaudits for his Beethoven Perspectives recitals on disc and at major halls and festivals, and is also much sought-after as a chamber musician.

Haefliger was born into a distinguished Swiss musical family and grew up in Germany, going on to study at the Juilliard School in New York. He was quickly recognised as a pianist of the first rank, and engagements with major US orchestras followed swiftly – the New York Philharmonic, Cleveland Orchestra, Los Angeles Philharmonic, Boston Symphony, Pittsburgh, Chicago and the San Francisco Symphony Orchestras among them. In his native Europe too, Haefliger has appeared with the great orchestras and festivals such as the Royal Concertgebouw, Rotterdam Philharmonic, Munich Philharmonic, Budapest Festival Orchestra, Deutsche Symphonie-Orchester Berlin, Orchestre de Paris, London Symphony Orchestra and Vienna Symphony. He is well recognised as a superb recitalist, making his New York debut in 1988. He has ongoing regular relationships with the Lucerne and Edinburgh Festivals, Vienna Konzerthaus, and other major halls across North America and Asia. Together with violinist Hilary Hahn he will perform Beethoven sonatas on tour in Japan and Europe in 2021/22.

Haefliger is a regular visitor to London’s Wigmore Hall with his ‘Perspectives’ series, in which he performs the complete piano works of Beethoven alongside works by other composers from Mozart to Ligeti. This series has formed the focus of Haefliger’s solo recital appearances and recordings in recent years, the latest CD being volume 7 of the series, released by BIS in 2018.

Haefliger was in a cabin in the Swiss Alps when Coronavirus struck in March 2020. Even though regretting the concerts he could no longer play (which included Beethoven with the Philharmonia and Esa Pekka Salonen, a concerto tour to Shanghai, Guangzhou and Beijing, and festival appearances in Edinburgh, Luzern and Chicago) – he used this period of enforced reflection to work on Beethoven’s monumental Hammerklavier Sonata op.106, culminating in an art movie of his performance and the Alpine surroundings. The film is being taken up by cinemas and TV stations and received its world premiere streaming at the Aspen Festival 2020 in place of his planned live recital.

This Autumn BIS Records (with whom Haefliger has an exclusive contract) release the world premiere recording of Dieter Ammann’s Gran Toccata with Susanna Malkki and the Helsinki Philharmonic, coupled with concerti by Bartok and Ravel. Haefliger gave the first live performance of the Ammann at the BBC Proms 2019 with the BBC Symphony and Sakari Oramo, closely followed by the North American premiere with the Boston Symphony and Susanna Malkki. It was co-commissioned for Haefliger by Boston together with the Wiener Konzerthaus, Munich Philharmonic, Lucerne Festival and Taipei Symphony.

Haefliger began his career with Sony Classical recording Mozart sonatas followed by Schumann Davidsbündlertanze and Fantasiestücke, Schubert Impromptus, and music by Sofia Gubaidulina. Later Haefliger recorded for Decca with the Takács Quartet and also Matthias Goerne, winning the Preis Der Deutschen Schallplattenkritik for their disc of Schubert Goethe Songs. His next planned recording will be early Beethoven sonatas for BIS in Autumn 2020.

Renowned as an interpreter of the French repertoire, Haguenauer’s recordings of the complete piano music of Debussy are in progress. He has also recorded solo repertoire by Liszt (transcriptions of the first two Beethoven symphonies) and chamber repertoire by Weber, Bloch, Ropartz, Stravinsky, and many others. A Beethoven and Schumann CD (An die ferne Geliebte, Dichterliebe, Fantasy Op.17), with the French tenor Gilles Ragon, was released in 2010 (Saphir). The first complete recording of Debussy’s melodies, the four-CD Claude Debussy: Melodies Integrale (Complete Songs), with some of the best French singers of our time, was released in 2014. The project was supported in part by a New Frontiers in Arts and Humanities grant.

Haguenauer was the subject of the feature film La Spirale du Pianiste, which continues to be shown in theaters throughout France. Haguenauer has been a member of the piano faculty at the Jacobs School of Music of Indiana University, Bloomington (USA) since 1998 and previously was professor of piano at the Strasbourg Conservatory.
