It's 2007 when David Moufang and Benjamin Brunn walk into Smallville Records in Hamburg and hear their own album playing in the shop. Nothing unusual about that, except that until that moment the record seemed to have vanished from music circuits entirely. Released the previous year on BineMusic, "Let's Call It A Day" was born out of four days of studio sessions dated February 2006: a series of jams with no preliminary conceptual blueprint. An instinctive work, built on extended takes, often running past the ten-minute mark, from which at most a few passages were trimmed, with no overdubs.
In an interview, David explains that this is, for him, the only sensible way to approach a collaboration: everything has to happen in real time, otherwise you risk ending up with two half solo albums glued together. Moufang was born in 1966 in the university city of Heidelberg, in southern Germany. His first musical horizon was tied to physical instruments — drums, guitar and piano — before a gradual shift into electronics, fuelled by an interest in technology and science fiction.
In the Nineties he became a reference figure with the Deep Space Network project, whose 1993 "Big Rooms" and 1996 collaboration with The Higher Intelligence Agency remain emblematic: an ambient techno designed for long-haul mental journeys, underpinned by real technical know-how. His debut solo album arrived in 1995 with "Kunststoff", suspended between IDM, deep house and ambient. Collaborations followed with Pete Namlook for Fax +49-69/450464 and with Jonah Sharp for Reagenz.
From interviews emerges the profile of a reserved sound craftsman, armed with an SAE diploma in audio engineering and a constellation of projects often released in limited runs. On the other side stands Brunn, born in 1977 in the small Saxon town of Mittweida, who studied piano as a child and, in the mid-Nineties, came into contact with Detroit techno and Chicago house, as well as with the releases of Kompakt, a label central to defining the reductionist language of the Noughties. On top of that came the Chemnitz scene and the VOXXX club, decisive in his formative years: a place where techno, house and more experimental hybrid forms coexisted.
It's there that Brunn developed the idea of electronics as architecture, as atmosphere. The turning point came with the Clavia Nord Modular synthesizer, with which, starting in '99, he began building self-generating patches, structures capable of moving on their own or being steered in real time. Brunn's are semi-autonomous systems based on continuous micro-mutations, which he himself describes letting flow for hours on end, capturing only the moments when a convincing tonal balance takes hold. During those years he released mostly through BineMusic, a label perfectly attuned to his slow, meditative approach.
Works like "Fahrstuhlmusik" from 1999 and "König Und Drache" from 2004 reveal a refined sensibility, in which the boundaries between ambient, dub, deep house and IDM remain deliberately blurred. This brings us to 2006, the year of the session from which "Let's Call It A Day" and the follow-up "Songs From The Beehive" were drawn. More than a collection of tracks, it's a sequence of sonic states, a continuous flow born of the same improvisation. Opening the record is "C-Sick", as welcoming as a dip into warm water. A soft drift made of dub chords, barely perceptible pulses and an almost total absence of kick drum, held up by a bed of low frequencies that envelops the listening experience.

It's as if Basic Channel's Maurizio project had been stripped of its kick drum, letting a more nocturnal, blue note phrasing come to the surface. "On The Magic Bus" moves along dub-house coordinates, with jazzy chords suspended over a pad and a rhythm that always holds itself back. The beat is there, but it never takes command: no climax, just an intimate journey toward a calm, peaceful horizon, far removed from the abrasive energy of the rave era just gone by.
The seventeen minutes of "Magnetically Levitated Train" represent one of the most emotional and melodic moments of the work, with soft harmonies laid over minimal percussion. It's an improvisation of subtle variations and delicate tensions. The instruments seem to answer one another in hypnotic fashion: with every melodic shift, the others realign naturally. The track abandons any formal scaffolding: no canonical development, just a free form made of extended zones of stillness.
Here the pair's atmospheric microsound reaches one of its most accomplished expressions: the pulse moves forward without pushing, while the harmonies slowly rotate on themselves, with minimal shifts in colour, as if the entire flow were deliberately refusing any final resolution. "A" is one of the shortest tracks in the set (just under seven minutes), a repetitive figure of synthesizers stripped down to the essentials. It would take very little to break its balance, and the deliberate choice not to add anything to the faint crescendo is evident: the insistent chord, the muted crackle of the filtered drum machine, the few ethereal touches floating at the edges. "Ω" is its conceptual continuation, with a very similar rhythmic section, reformulated into a logic of continuous, uniform movement of chords, hisses and drones. Here deep techno is defined in its most abstract sense: a deep, atmospheric art, threaded through with a constant rhythmic weave.
In "Grains" the contrasts emerge between what remains of a fragmented dub techno and sounds that first flash like electrical discharges, then dissolve into reverberated interference. The electroacoustic echoes and evident glitches speak to the poetics of Thomas Fehlmann and Moritz von Oswald, but with an attentiveness that also looks towards Ryoji Ikeda. The title track, "Let's Call It A Day", sums up the journey: clicks, hisses, urban and meditative atmospheres, suspended yet present in the sub frequencies; magnetic and rarefied, it closes out one of the most inspired sessions of the Noughties. Smallville Records, the very label where the two recognised their album a year after its release, reissued the work in 2020 with a different track order, marking a long-overdue critical reassessment.
