Having spent much of her youth deep in Cologne’s techno scene while staying connected to Georgia’s electronic music culture, Mariami brings a blend of both influences to her sets—carefully built, emotive and textured.
Since 2021, she has been part of the Brutalism label, where she also curates events across West Germany.
Her sound is subtle yet forceful, emotional yet controlled. Long transitions and contrast-driven selections define her approach, moving fluidly between atmospheric rhythms and heavier, percussive elements.
Måtyrer is a pioneering artist and co-founder of the Brutalism movement, known for pushing boundaries in electronic music and cultivating immersive experiences. With over a decade of background, Måtyrer has established a dynamic presence as a resident at Cologne’s iconic Gewölbe Club, where he also founded Research, a monthly community-centered Sunday party that has become a staple in the local scene.

Mohammad Reza Mortazavi (b. 1979, Iran) is known for his groundbreaking work with the tombak and daf, traditional Persian drums that he has radically redefined through new playing techniques and extended vocabulary. Mortazavi began playing the tombak at the age of six. By nine, he had already outpaced his teacher and won Iran’s national tombak competition—a distinction he would earn six more times. His new album Nexus evokes a meeting point where energies, times, and spaces converge. Mortazavi has performed at major venues such as the Berlin Philharmonie, Paris Panthéon, and Sydney Opera House, and his rhythmic explorations have led to collaborations with experimental electronic artists including Burnt Friedman and Mark Fell. He has just released Swamp (Ricardo Villalobos Variation) via
Justin navigates abstract sonic environments with a focus on texture, space, and storytelling.
Her work blends immersive soundscapes with an experimental approach to sound processing to
evoke sensory and emotive states.
From staging concerts in brutalist buildings -most notably Cologne’s St. Gertrud Church—to developing new technical setups such as spatial audio and collaborating with international artists, Brutalism’s work explores the interplay between sound and space.
At the heart of their practice is the understanding of brutalist architecture not merely as a backdrop, but as an active agent within our events. Through this approach, Brutalism have established a format that bridges pop and club culture, experimental music and theoretical reflection, opening up new connections and engaging diverse audiences.
