Since 2009, Vilma and Daniel Zbinden have performed as a piano duo at the International Čiurlionis Festival in Druskininkai, at the Festivalis Sugrižimai in Vilnius and Kaunas, at the International Pažaislis Festival in Kaunas, at the International St. Christopher Summer Festival in Vilnius and in the concert series at Užutrakis Castle. Another specialty of the ensemble is the performance of sometimes rare literature for choir / vocal ensemble or orchestra / instrumental ensemble and piano four-hands. In various formations they have played the Liebeslieder waltzes by Johannes Brahms, the “Lenz- und Liebeslieder” by Hans Huber, the “Minnespiel” by Heinrich Hofmann and vocal works by Florent Schmitt and Jean Français. Commented performances of the “Carnaval des animaux” for school classes are also on the agenda of the piano duo Vilma & Daniel Zbinden. The duo also plays double concertos by Mozart and Koželuh with the New Zurich Orchestra, the Glarus Chamber Orchestra and other Swiss and Lithuanian orchestras, and can be heard regularly on Radio Swissclassic. Fabian Müller wrote “Twelve Sounding Pictures” for the piano duo Zbinden, which was premiered as a melodrama in conjunction with “The Spirit on the Mountain” by Tim Krohn at the Braunwald Music Weeks in 2014, as well as a Concertino for cello, piano four hands and string orchestra, which was premiered in 2018 in Kaunas (Lithuania) with the cellist Pi-Chin Chien, the piano duo Zbinden and the VDU Chamber Orchestra under Jonas Janulevičius. Alfred Schweizer wrote a piece for piano four hands and orchestra for the piano duo Zbinden, which was played by the Glarus Chamber Orchestra under Reto Cuonz and by the Winterthur Orchestra Society under Volker Messerknecht. Together with the Belgian piano duo Irina Venckus / Patrik Aendekerk and Kęstutis Grybauskas, professor at the Lithuanian Academy of Music in Vilnius, Vilma and Daniel Zbinden play in the “European Pianist Ensemble”, for example in Zurich and Lucerne (International Conference of European Piano Teachers) or in Užutrakis Castle (Lithuania). Since there are only a few original works for eight hands on a single piano, Kęstutis Grybauskas has arranged ballet music and orchestral works. Fantasias on folk songs from Lithuania and Switzerland for piano six hands were premiered as compositions by Kęstutis Grybauskas in 2014. Another hobbyhorse of the piano duo is the composer Joachim Raff, whose works Vilma and Daniel Zbinden often combine with the reading of texts by Raff's contemporaries. The piano duo Vilma & Daniel Zbinden have recorded two CDs (see discography). The couple lives in Glarus and teaches at the Glarus Music School.
