After a six-year hiatus, Efdemin returns with »Poly« — his fifth studio album, released on the recently revived Berghain-affiliated label, Ostgut Ton.

As the title suggests, »Poly« explores multiplicity: of rhythm, texture, style, and emotion. Across eleven meticulously sculpted textures, the album weaves a multidimensional web of sonic references, nodding to the origins of techno while pushing resolutely into uncharted terrain. »Poly« feels like an afterglow—of decades on the dancefloor, of restless sonic exploration, and of a profound connection to the spaces and communities that have shaped Efdemin’s sound.

Over the course of 60 minutes we are taken through different territories and landscapes of sound. Mysterious and swirling, abstract and droning textures over at times fast and stoic rhythmic concepts. Sometimes the sunlight breaks into the opaque and mysterious soundscapes before the pulse is taken over and sucks us back straight into the club.

The overall tone of »Poly« is mild and playful, introvert and at times dreamy. The music is rich in sonic expression and breathes the spirit of musical concepts that have been refined over the course of decades. What Sollmann has condensed here feels like a culmination of his multilayered and polyphonic personality situated between club, museum, studio, and academy.

The album cover features a striking photograph of a human ear by renowned German artist Isa Genzken. Known for her radical visual language, Genzken’s work here functions as a metaphor for deep listening. The ear symbolises the layered complexity and immersive quality of the music on »Poly« — an invitation to perceive sound in all its depth, fragility, and force, and unlock its potential to unite different voices in a distorted reality.
