Celebrating a wild 13 years of Kater with a run through from Friday night until Tuesday morning. 77 hours of music and wild abandon not to be missed! This year we are particularly excited to have (almost) ALL our residents joining us – this time, in unlikely b2b combinations that are sure to surprise you. The Sunday open air is of course a highlight, and we are happy to have ELIF joining us alongside Chris Schwarzwälder b2b Foolik, Britta Arnold b2b Sascha Cawa! The musical program also leaves nothing to be desired: electro-EBM madness from The Hacker, deep house from Armen Miran, stellar house and techno selections from Cassy, acid and italo house from Demi Riquisimo, and a very special secret live act on Saturday night that you won’t want to miss! Hopper on Friday night is for lovers of deep and melodic sounds, on Saturday night it’s more about EBM, electro and italo and on Sunday night it’s gonna be harder and faster with Pascal Hetzel, BODYSHIFT and Mila Stern b2b Sheila! If minimal and tech house is your groove, you’ll be at home in Acid Bogen on Saturday daytime with Karina & Marc Schneider, Bonjour Ben and Iron Curtis. Sunday night also won’t be short on good vibes house and disco music with Elizen the Emperor, Farida Bady (live), and go looking for some extra fun with Nadine, Mark Gill b2b Enzio Etchaberri and many, many more! Keep your eyes open for pop up performances throughout the weekend (did someone say jelly fight?!) Dress up as your favourite Greek god, pack your pickles, or just come as you are - we can’t wait to party with you!
