Andreas Fischer studied Voice and Music Education in Stuttgart and in Vienna. Even as a student, his interest in contemporary music and working closely with composers had become a central aspect of his work. He has performed in numerous world premieres as a member of the Neue Vocalsolisten Stuttgart and as a soloist and conductor.

With the role of the father in Chaya Czernowin’s opera Zaide/Adama he debuted in 2006 at the Salzburger Festspiele. With the same production he gave a guest performance at the Theater Basel in 2007 and in spring 2008 performed again in the re-production of the same opera at the Theater Bremen; followed by premieres of Enno Poppe’s opera Arbeit, Nahrung, Wohnung and Aura, the opera by José Maria Sanchez-Verdú.
