Officially called the International Festival of Contemporary Music, the Warsaw Autumn Festival‘s offerings in its early years were more conservative than the name would seem to indicate. Today more experimental music and world premieres are performed along with classical standbys of the 20th century. It was established in 1956 by a group of Polish composers who wanted to bring other East European as well as West European countries together. The concerts are held in the National Philharmonic building, the Royal Castle, and other venues around the city. Discuss
