Linz's Cloud of Sound is a free open-air music event in Donaupark each September, pairing live orchestral performance transmitted from the Brucknerhaus with lasers, fireworks, projections and boats staged along the Danube. A separate indoor classical concert and a children's afternoon edition round out the same days.
On September 18, 1979, roughly 100,000 people gathered in Linz's Donaupark to listen to a studio recording of Bruckner's Symphony No.
The outdoor visualized concert stages a new narrative theme every year using lasers, fireworks, video projections and boats on the Danube itself as part of the staging -- a scale of production unusual for an event with no admission charge anywhere in it
It splits into three linked formats held across the same days: the visualized outdoor spectacle, a classical concert performed without effects inside the Brucknerhaus, and a children's afternoon edition running since 1998
The whole tradition traces directly to a 1979 broadcast that drew roughly 100,000 listeners to a studio recording played through a purpose-built sound system rather than a live performance
The event's format -- live orchestral music transmitted from the Brucknerhaus and staged outdoors with fireworks
lasers and a new visual narrative each year -- has continued largely unbroken since the early 1980s
making it one of the longest-running traditions of its kind in Austria
