NOA (New Opera Action) – contemporary alternative opera and interdisciplinary art festival, which gave rise to Operomanija movement in 2008. Crossing the borders of traditional opera and searching for interdisciplinary crossings, the festival declares freedom, collective creation, openness to diverse ideas and forms of cooperation. Uninhibited by any framework and unwilling to restrict itself via topical, temporal or format references, the festival mostly presents world premieres of diverse productions.
