Ostravska banda was formed in 2005 by Petr Kotík as the resident chamber orchestra for the biennial Ostrava Days, Ostravská banda consists of young musicians from Europe and U.S. whose primary interest is the performance of new music. Apart from the orchestra’s artistic director, Petr Kotík, Ostravská banda has also worked with conductors Roland Kluttig, Peter Rundel, Ondřej Vrabec, Barbara Kler, and Johannes Kalitzke. The repertoire includes composers of the 20th century (John Cage, Elliot Carter, Morton Feldman, György Ligeti, Luigi Nono, Edgard Varèse, and Iannis Xenakis, among others) and our contemporaries (including Louis Andriessen, Petr Kotík, Alvin Lucier, Tristan Murail, Phill Niblock, Christian Wolff, Salvatore Sciarrino, Wolfgang Rihm, Martin Smolka, Miroslav Srnka, and Petr Bakla). Apart from regular performances at Ostrava Days festivals, Ostravská banda performs and tours at such venues as the Paris Conservatoire, Carnegie Hall and Lincoln Center in New York, Akademie der Künste in Berlin, Vredenburg Music Centre in Utrecht, musicadhoy in Madrid, and Prague Spring, to name just a few. Ostravská banda performed as an opera orchestra for the first time in 2012, for the first biennial NODO Festival (New Opera Days Ostrava).

NODO has been established by Ostrava Center for New Music in cooperation with National Moravian-Silesian Theatre. In the 2012/2013 season, Ostravská banda performed at the Beyond Cage festival in New York in the autumn; in January, it gave five world premieres for the WDR 3 Cologne radio station and it appeared again at the Prague Spring 2013 festival in the Archa Theater.
