The annual festival takes place on the grounds of Schloss Grafenegg.

Two venues have been built particularly for the festival in the park of the castle: The open-air stage Wolkenturm (capacity 2,000 in total, opened 2007)[1] as well as the new concert hall Auditorium (capacity 1,372, opened 2008).

The festival's program consists of symphonic and chamber music as well as recitals.

The festival also serves as the major introduction of the annual Grafenegg composer in residence.

During the festivities the composer in residence presents various newly commissioned works and holds exclusive workshops for young composers and conductors.
