Performing with young Austrian soloists and the Wiener Singakademie is one of the main concerns of the orchestra. For 2009 Heinz Ferlesch and his orchestra have been invited to perform at the International Baroque Festival at the monastery of Melk. Various CD recordings and broadcasts show the wide range of the orchestra´s repertoire: in 2004 the orchestra has recorded music by Antonio Vivaldi for the Austrian broadcasting station ORF, in 2006 a live recording of Handel´s „Judas Maccabaeus“ has been released by the ORF Edition of Ancient Music. In 2009 a recording of Handel´s oratorio “Alexander´s Feast” has been published.

This mixed choir is focusing on A-capella music and has been invited to Festspielhaus St. Pölten, to the Brucknerhaus Linz and various festivals, e.g. Europäischer Kultursommer Aspach, Passauer Konzertwinter and Kultursommer St. Paul. Concert tours took the choir to England, Italy, Greece and Germany. Conductor Heinz Ferlesch and his ensembles have been awarded various national and international prizes.

In 2007 he was awarded the highly respected Ferdinand-Grossmann prize. In 2009 Heinz Ferlesch was awarded in the context of his activities for the choir scene Lower Austria with the Erwin Ortner price to the promotion of the choir music.
