Having recorded with Allez-Allez and with the more dubious sounding Snoretex moniker, Sam Willis now releases his debut album proper simply as Sam Willis. Not the most distinctive name, so for those who don't know he is most frequently found busying himself behind a plethora of dials and a mesh of electronic wizardry beside fellow technician and guitarist Alessio Natalizia as one half of the brilliant Kompakt duo Walls. Winterval sees him go it alone with no alias to hide behind, and the result is the equal of anything he’s so far been a part of.

Without Walls' characteristic soporific guitar washes there was always the chance that this album would be more straight forwardly techno and lose some of the diversity of Coracle. Fortunately this is not the case. Melding house, techno, minimal and Balearic influences within an incubator like ambience, Winterval creates an otherworldly electronic hinterland in which the organic and synthetic coalesce, producing a sound that is not easily defined.

'Hello Wendy' plunges straight in to the ice cold undercurrents that underpin the album, undercurrents populated by echoes, reverb and electronic glitches and end with the looping disembodied transmission repeating the phrase "Hello Wendy." This is a beautifully alluring track, yet there’s also something unnerving at work here. Absorbing from the start there's a sense you can't turn back, the steadily building beat and morphing layers of more decorative synth in 'Weird Science' dragging you deeper and deeper into the abyss. 'Foxglissandro' combines the complex percussive loops of Luke Abbott with the shimmering tones of Italian band Esperanza while there is even a hint of Balearic with 'Seven Down and Six Across', a sort of subdued, sub-aquatic version of Caribou's 'Kaili'. Here Willis masters the art of sustaining a beat and rhythm, prolonging the promise of a euphoric climax without losing any interest through repetition and maintaining the more unnerving sides to his sound.

Nowhere is this aesthetic clearer than on the title track. The longest on the album, a deliciously techno beat guides us through a labyrinth of samples, echoes, muffled voices and mechanical whirring. The sense of anticipation is unrelenting and though not offering any tangible apex, if you had to pick a standout track it would probably be this. Finally comes the strange polar séance of 'Twirled With Your Slight Fingers' possessing indecipherable murmuring and bitterly cold reverberations as the album seeps away in an amorphous haze.

At times Winterval sounds like it could be the soundtrack to a piece of visual art (Sam has contributed music with Alessio to a Tate Modern installation) and at others like something emanating from an Antarctic nightclub. Either way it is a cohesive record that will not disappoint fans of Walls and should help make Sam Willis a more immediately recognizable name.
