Lineup
Hidden Empire
Not your typical techno/house act, Branko and Niklas, alias Hidden Empire, have established a sound signature at once abstract and alluringly dynamic over the years, gathering momentum through a handful of quality releases for an array of international labels. Since the drop of their first records back in 2015, Branko and Niklas have been championing a sound both genuinely turned towards the club while allowing themselves to explore into further adventurous territories – from dreamy, cosmic excursions to a versatile arsenal of foundation-shaking EBM cuts, via exotic detours and back to the classic, floor-focused programming that flows through all of their ambitious, stadium-sized output. The pair’s wide-screen vision shows Branko and Niklas’ impeccable sense for crafting sonics that far surpass mere DJ functionality to print into the listener’s mind durably.
Dirty Doering

SKALA
Coming from the vibrant city of Berlin, SKALA is a visionary music producer, vocalist, and DJ whose core mission is to catalyze emotional openness, which she likes to call "eSKALAtion." Starting her musical journey as a child, she blends classical piano skills with modern electronic music. SKALA's music is a masterful fusion of organic percussions, glitchy elements, and synthesized leads, creating a soundscape marked by heavy bass lines and airy melodies. Her tracks made it several times to the Beatport Top 50 Charts in Melodic Techno and Electronica. In 2023, SKALA expanded her influence in the music industry by co- founding the label Amaeo with her partner Theologos. This new venture aims to introduce innovative music and support emerging artists in the industry. SKALA's global reach as a performer is impressive. She has played at major venues and events around the world, including Off Sonar in Barcelona, Klein Phonix in Istanbul, Electric Brixton in London and did multiple tours across India, Central America, Europe, and various countries in the Middle East. Her international tours not only showcase her dynamic range as a DJ but also bring her unique sound and emotional resonance to a global audience.

Solvane
Solvane's activities are moved by passion. Keeping his style versatile and emotional, allowed him to play the big stages around the globe; from Burning Man Festival to Fusion, from European capitals like London, Paris and Istanbul to Australia, Asia and the USA. Solvane has been on stage since his teen years and discovered his enthusiasm for electronic music in his early twenties . The different musical influences throughout his life inspired him to constantly expirement and evolve the style of bis music. The connection to his chosen home Berlin is alive and kicking: he not only plays regularly at his Ritter Butzke residence but also has been creating tracks that have been supported by top-league acts like Claptone, Kollektiv Turmstraße and Acid Pauli for more than 10 years and counting . In 2016 Solvane reached the Top 20 Electronica Charts on Beatport for the first time, and came to stay: his tracks have been consistently honored with top rankings. After several Singles and EPs on labels like „Light My Fire“ and „Ritter Butzke Studio“ he moved on to Oliver Koletzki's label „Stil vor Talent“. The tracks' success lead to an exciting first in the end of 2017: a Japan tour.

Markus Klee
Markus Klee is quickly becoming a synonym for energizing groovy techno and tech house. The Berlin-based DJ and producer has been part of the Berlin electronic music scene for many years now and has since then become simply irreplaceable. His first experiences as a DJ were however as spontaneous and coincidental as could be: his talents came to surface during several after hour parties, where he would perfect his skills and experiment on a self-taught basis. Markus Klee is well known for demonstrating great expertise and performing in Berlin clubs like Ritter Butzke, IPSE, Suicide Circus or Weekend, which in turn allowed him to become a guest DJ in Munich’s best clubs and has given him the opportunity to successfully showcase his talents internationally in countries like Italy, Spain, Netherlands, Austria, Serbia and Switzerland. In early 2015 he began releasing his very own tracks on his very own label, Konzeptions, which he co-founded along with SoKool and Mr. Schug. He has additionally released tracks on labels like Lapsus Music & Patent Skillz.
Malouna
OLEA
Since officially stepping behind the decks in 2023, she has rapidly gained attention with her emotionally charged and rhythmically intense sets. OLEA has become an integral part of the Hamburg and Frankfurt underground scene, while also expanding her footprint across Germany and beyond. Internationally, OLEA left her mark on Australia’s club scene during her 2025 tour, performing not only at the legendary Revolver Upstairs in Melbourne, but also at several other renowned venues across Melbourne and Sydney, further expanding her international reach and sonic footprint. Highlights of her growing career include performances at Ritter Butzke Berlin, the Katermukke Festival at Tanzhaus West, and the WEIRD Showcase at Hamburg’s iconic Uebel & Gefährlich. She has shared the stage with acclaimed artists such as Victor Ruiz, Sven Väth, Anna Reusch, Hidden Empire, Mark Blair, Township Rebellion and Kaufmann - steadily carving out a name for herself in the global electronic music landscape. OLEA’s sound is defined by a captivating contrast: dreamy melodies and hypnotic vocals layered over deep, pulsating, driving basslines. Drawing inspiration from '80s textures to contemporary techno structures, her sets invite listeners on an immersive journey that’s as powerful as it is emotive. Her performances are shaped by a deep sense of freedom, connection, and vulnerability.
