The goal of NODO/New Opera Days Ostrava festival is to contribute to the discussion about the evolution of opera and to demonstrate its possibilities in the 21st century. Since 2012, the biennial festival has been alternating with Ostrava Days, which largely focuses on concert music. NODO is an Ostrava Center for New Music production co-organized by The National Moravian-Silesian Theatre and constitutes the only festival of its kind in the Czech Republic.
NODO features Czech or world premieres and presents both concert versions and full stage renditions at venues ranging from traditional theaters to industrial spaces. It also stimulates the production of new works for the festival: Martin Smolka, Petr Kotík, Petr Cígler, František Chaloupka or Idin Samimi Mofakham have all penned operas for NODO. The festival has provided Czech theater-goers with the opportunity to experience operas by John Cage, Salvatore Sciarrino, Bernhard Lang, Richard Ayres, Rudolf Komorous or Iannis Xenakis for the first time; NODO also commissions new works by young composers and brings together novel production teams that defy opera-world traditions.
