The young St. Pölten native, Johannes Bamberger, began his vocal training at the music school in his hometown before continuing under Bernd Oliver Fröhlich in Vienna. Since 2013, he has been studying solo singing at the University of Music and Performing Arts Vienna under Bernhard Adler and Rainer Trost. In 2016, he performed the role of Bardolfo in Verdi's Falstaff at the Schönbrunn Palace Theatre and made his debut as Don Ottavio in Mozart's Don Giovanni there as well.

In 2015, under the direction of Domkapellmeister Otto Kargl, he sang the tenor arias in J.S. Bach's St. Matthew Passion at the Festspielhaus St. Pölten, and the following year, he performed as a tenor soloist in Mendelssohn Bartholdy's Elijah at St. Pölten Cathedral. He has also successfully debuted as the Evangelist in Bach's Christmas Oratorio and as a soloist in Handel's Messiah. In 2015, he was invited by the "Fritz Wunderlich Society" to perform at the first "Fritz Wunderlich Music Days" in Kusel, Germany.
In 2017, he made debuts as Belmonte in Mozart's The Abduction from the Seraglio as part of an MDW production and as an aria soloist in Bach's St. John Passion at the Festspielhaus St. Pölten.
