There is always a calculated "risk" in assembling three distinct sonic alchemists into a single, uninterrupted evening. Music, after all, operates in two conflicting dimensions. Some tracks act as brutal, subterranean time-machines, conjuring from the faded debris of your unconscious mind the ghosts of forgotten rooms, abandoned lovers, and tropical nights long since sealed away. Other music does something altogether more terrifying: it tears you clean out of the familiar space-time continuum, leaving you with no past to lean on, only an uncharted, hallucinatory present to experience from scratch. To curate a lineup that toggles between these two states is to invite a volatile, high-altitude vertigo. Welcome to Berlin Summer Air III: Moments & Memories.

Returning from his latest solitary expedition into the sonic unknown, Luis Rosenberg steps into the fray like an obsessive, world-weary ethnographer of sound. His crates are notorious – a sprawling, unpredictable archive of the obscure, the ancient, and the thoroughly bizarre, scavenged from dusty street markets, forgotten analog tapes, and remote corners of the globe. Rosenberg does not merely play tracks; he unearths anomalies. His sets are ever-shifting, never-repeated sonic maps designed to pull the listener through unexpected geographic shifts, blending organic field-recorded textures with low-slung, hypnotic rhythms.

When the sun dips and the chill of the Berlin evening sets in, the responsibility of kindling the periphery of the fire falls to our old friend Constantin Sayn-Wittgenstein, better known to the night-walking cognoscenti as Mr. Laboso. Possessed of an effortless, aristocratic affinity for heavy funk and low-end heat, Laboso’s reputation precedes him. One recalls his heroic tour of duty in the humid jungles of Tulum, holding court at the infamous Papaya Playa Project. There, amidst the tropical rot and oceanic salt, his noble, self-assigned mission was to keep the dancing subjects cool in their heads and structurally intact, lest the sheer, oppressive heat turn them into literal vapors. Few selectors handle such high-stakes physical stewardship with more style, humor, or ruthless efficiency.

Setting the stage for this three-act odyssey is Mattmosphere, taking control of the console at 7:00 PM. Fresh from the lake-side dreamscape of Garbicz Festival, he arrives with the mud of the woods barely dry on his boots and a mind brimming with low-BPM, atmospheric alchemy.

But before he steps up to orchestrate our collective slowdown, we cornered him for a moment of quiet, concentrated introspection – a chance to untangle the philosophy, the travels, and the deep-seated rhythm behind the man. What emerged from that conversation was a manifesto for the modern, weary raver – the story of how a basketball-playing drummer from a rock-and-roll household ended up crafting Berlin’s most delicate, metaphysical dancefloors.

In an era where electronic music often defaults to the sterile, machine-gun tyranny of 140-BPM techno, the origin story of the Berlin-based selector known as Mattmosphere (born Matti) reads like a deliberate, circuitous rebellion. Raised in a household bathed in live instrumentation – where a multi-instrumentalist father served up steady diets of swampy 1970s rock, Dire Straits, psychedelic jazz, and global rhythms – young Matti absorbed sound not as a digital algorithm, but as a living, organic ecosystem.

Taking to the drums early on, he developed a sharp, bone-deep intuition for pocket, syncopation, and groove. A subsequent detour through the court-side asphalt subcultures of basketball introduced him to the gritty, vocal cadences of golden-era hip-hop. Yet beneath the rhythmic swagger lay a quiet, persistent yearning for something altogether more ethereal: a drive toward smooth, low-slung, atmospheric soundscapes designed to coax the human psyche into a state of dreamlike weightlessness.

Inevitably, his trajectory dragged him into the gravitational pull of Berlin – the sprawling, sleepless mecca of international nightlife. In a metropolis dominated by cavernous concrete bunkers and relentless 72-hour techno marathons, it is remarkably easy for a DJ to get locked into a single, claustrophobic aesthetic. Mattmosphere flatly refused the trap. Treating Berlin not as a prison of style but as an extended collaborative laboratory, he gravitated toward open-air, sun-drenched roosts like Klunkerkranich and his home base with the Akasha Berlin family, balancing these local sanctuaries with a relentless, nomadic impulse to travel. Wandering through foreign cities and distant cultures became his essential anti-toxin against artistic stagnation, fueling a sound that stretches far beyond the predictable grey boundaries of standard German club fare.

His sets – frequently heard floating over the sun-drenched lakeside stages of Garbicz, the legendary Dubstation at Fusion, or Bucht der Träumer – represent a radical philosophical departure from the dancefloor’s traditional, punishing industrialism. Where typical club music demands physical submission to a metallic, robotic grid, Mattmosphere deploys slow-cooked, airy, and deeply reflective downtempo. Heavily seasoned with organic percussion, distant folk melodies, and ethno-inflected motifs, his selections mark an intriguing cultural shift. In an increasingly hyper-kinetic, burn-out-prone world, the modern audience no longer derives its ultimate catharsis from being battered by cold synthetics. Instead, ravers are seeking physical respite, turning to music that operates as a metaphysical sanctuary – a space to slow time, turn inward, and reclaim their own humanity.

What makes Mattmosphere such an effective conductor of this spiritual slowdown is his chameleon-like versatility, anchored by that early drummer’s precision. He reads a floor not as a crowd to be conquered with volume, but as a delicate, collective mind to be gently absorbed.

Effortlessly shifting between chilled fluidity, deep-dwelling mystical house, and world-weary organic textures, he weaves sets that feel less like club performances and more like shared, soul-to-soul conversations. In his hands, the dancefloor is transformed from an anonymous pit of hedonistic distraction into a quiet, synergetic network – proving that the most revolutionary thing a DJ can do in a mechanical city is to make the human heart beat at its own, natural speed.
