For over 25 years, David Madson (aka Odd Nosdam) has been stationed away from the light of the mainstream, diligently working the nightshift. Every so often, we awake to find another of his bleary and beautiful missives slung into the waking world – albums whose assemblages of sampled grooves, atmospheres and voices are unified by a hallucinatory sense of melody, like disparate visions strung together through ribbons of sleep-talk. From his earliest days as a member of the seminal group cLOUDDEAD, through his remixes for artists such as Boards of Canada and Black Moth Super Rainbow, Nosdam has been reporting back from his rounds upon the perimeters of culture and consciousness, forging a musical language all of his own.

On Patrol is the second Odd Nosdam LP to be released on The Notwist’s imprint Alien Transistor – following on from the 2019 album Mirrors – and continues a collaborative history that begun with a 2008 remix of The Notwist song, “Sleep”. It’s a love letter to the vinyl format, produced with the aim of optimizing for a single LP. This objective permeated every aspect of the album’s production, from the duration of each side through to the vinyl mastering (Jessica Thompson) and lacquer-cutting (Dubplates & Mastering, Berlin). As we've come to expect, the album is built almost entirely from found sounds, many of which were taken from obscure and second-hand vinyl gathered during Nosdam’s ceaseless crate-digging escapades. Other sources include field recordings made in 2022 at the Catalonia summer home of artist Salvador Dalí, which are baked into the swirling sci-fi glide of “Here to Know (Adéu Mix)”, and a sumptuous clunking bass line courtesy of Organi’s Mike Walti, which runs like an infinite highway through the fuzzy, sunbaked sprawl of “Deepsimple”.

Odd Nosdam’s work has always swept the entire atmospheric spectrum, from rhythmic vigour to levitational beauty. On Patrol is perhaps his finest assimilation of these extremes. “Sgt. Pepsi” is the perfect case in point: a formidable slow groove capsizes into vinyl crackle after a mere minute, before the song resurrects itself through sweeping strings and vocal harmonies, sliding against each other like the overlain romantic denouements to a dozen Hollywood films from the 1940s. Elsewhere, “Get You In (Belong Mix)” drapes shoegaze guitar over a trundling funk backbeat, straddling the physical world and the outer realms, while hushed voices point toward the song's implied themes of cultural cliques, critical consensus and the plight of the eternal outsider: “Sure, I can get you in... these people are my friends, I’m one of them - I belong.”

This is music that both endures and disappears. Odd Nosdam has always wielded a strange relationship with time, scrambling association with any specific era, weaving together numerous tempos simultaneously. There is no master clock. Each track could happily hold up as an infinite loop, yet Nosdam clearly favours the potency of the gone-too-soon, applying the fadeout just as hypnosis starts to crest. Indeed, the songs are both the product of meticulous long-term construction and spontaneity. While the foundations of On Patrol have come together over several years, the recording process involved channeling vibes through a vintage Roland Space Echo and bouncing song fragments back and forth from hard disk to cassette 8-track, gifting a phased permanence to creative decisions made on the fly – a hat-tip to the production processes of Nosdam's longtime hero, Lee ‘Scratch’ Perry. Like a recurring dream, On Patrol appeals to both the plains of momentary ephemera and the long-established backchannels of the unconscious, equal parts revelation and deja vu.
