"...and as exceptional soloists - showcasing 'á deux' their polished keyboard skills, but never themselves - the Hungarian/Swiss piano duo Adrienne Soós and Ivo Haag gave a resplendent rendition on two concert grands of Mozart's Piano Concerto in E-flat" (Marianne Mühlemann, Der Bund 14.12.2015)

The Hungarian/Swiss piano duo, Adrienne Soós and Ivo Haag, is fresh from successes at the Warsaw Philharmonic, the Lucerne Festival and with the Bern Symphony Orchestra under Mario Venzago. For a quarter of a century, the Soós Haag duo has been associated with both the rediscovery of well-known works and the exploration of remote corners of the repertoire. Whether championing the complete works of Schubert or lost masterpieces of the 19th and early 20th centuries, their quest is to bring the audience closer to the piano duo repertoire with all its breadth and significance. The duo also receives great acclaim for its large-scale projects, such as complete cycles of the four-hand piano works of Franz Schubert in 2011 and of Debussy/Ravel in 2014 in Boswil.
The Soós Haag duo has long established itself as one of Switzerland's leading chamber music ensembles and has helped to raise the profile of the piano duo genre, attaching equal importance to playing on two instruments and with four hands on one instrument. Beyond this, they regularly perform with orchestra, and sometimes extend their duo to form larger chamber ensembles through collaborations with singers and instrumentalists. They have made a name for themselves with their ambitious and individual programming, incorporating as a matter of course unjustly neglected works with standard repertoire. Over the years they have performed and recorded a wealth of such near-forgotten treasures. Commissions from renowned composers such as Dieter Ammann, Rudolf Kelterborn and Krzysztof Meyer complete the picture. The duo has worked for several years with the Geman label Telos Music. After a first CD with works by Béla Bartók they undertake a complete recording in four parts of the symphonies by Brahms in the composers own piano duo versions.
Their concert schedule has taken them to the Lucerne Festival, the Eisenstadt Haydn-Tage, the Hohenems Schubertiade, the Carinthian Summer Music Festival (2013 and 2015), the Musiktage Mondsee (artistic director András Schiff), the Zug Theater Casino, the Klavierissimo Festival in Wetzikon, the Sommets Musicaux in Gstaad, the Société de Musique in La Chaux-de-Fonds, the series Kammermusik Bern, the Ittinger Sonntagskonzerte and the Zurich Tonhalle-Gesellschaft amongst others.
They are invited to perform as soloists by such orchestras as the Filarmonica Toscanini Parma, Bern Symphony Orchestra, Lucerne Symphony Orchestra, Orchester Musikkollegium Winterthur, St. Gallen Symphony Orchestra, Zurich Chamber Orchestra, Camerata Bern, and Camerata Zurich, where they work with conductors including Mario Venzago, Jac van Steen and Peter Hirsch.
Ivo Haag was awarded the Zuger Werkjahr in 2008 for the work of the piano duo.
