Formed in 2005 by Petr Kotik as the resident chamber orchestra for the biennial Ostrava Days, Ostravská banda consists of young musicians from Europe and the U.S. whose primary interest is the performance of new music. Principal conductors are Petr Kotík, Roland Kluttig, Peter Rundel, Ondřej Vrabec, Johannes Kalitzke, and Barbara Kler. The core instrumentation of 24 players can change according the requirements of each score. The repertoire include composers of the 20th century: John Cage, Iannis Xenakis, Morton Feldman, Edgard Varese, Luigi Nono, and Gyorgy Ligeti, among others, and our contemporaries Louis Andriessen, Elliot Carter, Christian Wolff, Petr Kotik, Alvin Lucier, Phill Niblock, Martin Smolka, Miroslav Srnka, Peter Graham, and Petr Bakla, among many young and emerging composers. Apart from regular performances at Ostrava Days festivals, Ostravská banda performs and tours at such venues as the Paris Conservatoire, Zankel Hall at Carnegie Hall, Prague Spring Festival, Akademie der Künste in Berlin, Vredenburg in Utrecht, Alice Tully Hall at Lincoln Center, and musicadhoy in Madrid, to name just a few.
