The Festival Choir is linked with the baroque concerts of the Pannon Philharmonic, through a highly ambitious professional program, whereby the ensemble performed J.S. Bach's Christmas and Advent Cantatas. Emblematic works such as Bach’s Magnificat, the famous Actus Tragicus or Haydn’s Stabat Mater were also performed with the orchestra. The largest professional undertaking of the choir has been the processing and performing of Matthew's Passion by J.S.Bach, which is one of the most complex baroque vocal symphonic works. In addition to the two-choir apparatus, the greatest challenges is represented by the manifold task of the choir: beside to the usual chorales and starting and closing choir movements, the choir is also an active participant in dramatic processes, thus the authentic performance of different roles and perspectives makes it one of the hardest and most demanding masterpieces of J.S. Bach's.
