The inimitable Richard Youngs returns to Black Truffle with this third full-length for the label, Hidden. Like CXXI and Modern Sorrow, Hidden unfolds across two side-long pieces at once eminently listenable and possessed of the ‘bloody-minded’ dedication to ‘having an idea and sticking with it’ that Youngs himself has identified as one of the key qualities of his work.

At the core of both pieces are rapid, randomised arpeggios generated with a Moog Grandmother, hypnotic patterns that wouldn’t be out of place on a Berlin School classic. Alongside these arpeggios, across the seventeen minutes of the first side-long piece Youngs builds an airy structure of shakers, synthetic handclaps and a brief, repeated sample, impossible to identify but sounding like a glitched foghorn. Over the top we hear his unmistakable voice, repeating single syllables—Ha, Ho—with a slow delay, something like a lonely one-man-band take on Anthony Moore’s Pieces from the Cloudland Ballroom or a more musical elaboration of the hypnotically overlapping delayed phonemes of Anton Bruhin’s Rotomotor. Like much of Youngs' work, the arrangement of sounds is sparse, each layer punctuated by spaces that allow others to shine through, in a way that seems to have more to do with dub or early hip-hop than high-brow models of musical reductionism.

On the flipside, the arpeggios return, now accompanied by ringing, filtered guitar chords and long flute tones. The use of a similar ground layer across the two pieces with strikingly different overdubs calls up Youngs' first solo record, the classic Advent, reminding us of how consistent ‘theme and variations’ is as an approach in his enormous body of work. Joined by handclaps and a chiming sound, the piece almost feels like it is about to achieve dance-floor lift-off at times, only for the percussion to disappear and leave the listener once again floating among the guitar and flute, now joined by occasional cut-off vocal snippets, like a radio turned quickly on and off. The suspension of these disparate elements over the steady foundation of the Moog arpeggios might remind some listeners of the free-form studio explorations of Moebius & Plank and Holger Czukay or even give a nod to Youngs’ formative encounter with Cabaret Voltaire.

Like some of Youngs’ much-loved work with Simon Wickham-Smith, Hidden approaches relatively familiar sounds and instruments from skewed angles, delighting in loose structures of interaction that border on gleeful incoherence while remaining outwardly beautiful. Coming up to almost four decades of persistent activity, like little else in contemporary music Youngs’ work beams with the simple joys of exploration and experiment.
