Epica posted this Setlist detail on their blog for the Opera Rock Show:

Opera Rock Show Setlist partially revealed...

As previously stated, Epica are playing a special show with full orchestra and choir in Miskolc, Hungary on June 14th. In addition to the regular set of songs from their own repertoire (including a few orchestral songs from singles and "The Score", which have never been played live before) Epica will bring another 45 minutes of metal adaptations of classical songs and movie soundtracks, accompanied by the orchestra and choir. Without revealing everything we would like to give you an idea of what we will play:
