This is SOMMERLIGHTS 2022 at DARK MATTER. Featuring light pyramid STALACTITE. 

This year, Christopher Bauder's 16-metre-high light sculpture STALACTITE will float above the heads of the visitors on the outdoor grounds of DARK MATTER. DJs and other live acts will light up the pyramid with their music. In addition, there will be refreshing drinks and tasty snacks for some fine summer evenings under the open sky.
