The project HIDDEN VOICES / VOCI NASCOSTE presents members of the Opera Choir of the State Theatre Košice, who only occasionally sing minor solo characters in opera productions, in addition to their long-term performance in the Opera Choir.

The romantic ballet Giselle is a masterpiece of world ballet production. Among other things, it also carries a possibility to present completely different backgrounds, such as contrast between beauty and ugliness, love and hate, dream and reality, the world of fairies and rural environment.
