Helvetia gone wild! Together with KIKI and the 25hours Hotel Langstrasse, Klaus is hosting a 1 August celebration packed with mischief, surprises, and plenty of fun. Expect lots of amazing music from international and local artists and DJs across two dance floors.
And the best part? The party takes place both outdoors and indoors — right in the heart of it all, directly in front of the 25hours Hotel Langstrasse in Zurich.
