Lucy Duncombe and Feronia Wennborg compose a modern symphony for virtual choir on 'Joy, Oh I Missed You', muddling sound poetry with Nuno Canavarro and ‘Systemische'-style machine-damaged surrealism. It's mindbogglingly good, like a mashup of Lee Gamble's 'Models', Akira Rabelais' 'Spellewauerynsherde' and Robert Ashley's timeless 'Automatic Writing’ screwed to perfection in a mode that will also appeal if you’re into work by Kara-Lis Coverdale, Nozomu Matsumoto, Theo Burt, Olli Aarni, Sydney Spann, Hanne Lippard.

Duncombe and Wennborg have been chewing over ‘Joy, Oh I Missed You’ for four long years, working their process until they were "queasily intimate" with their arsenal of artificial voice tools. Tracing the history of the technology, from voice synthesisers and chatbots to AI voice analysis tools, the duo experiment relentlessly to develop a digital-age response to IRL extended vocal technique - think François Dufrêne, Yoko Ono or Phew. Less interested in replicating human sounds exactly, they instead test how various tools might cough up their own idiosyncratic tics as they stretch and stutter through attempts to mimic their "fleshware" counterparts.

Duncombe's got prior form here, most recently re-synthesising her voice on the brilliantly oily 'Sunset, She Exclaims' 45 for Modern Love, following a stunner for 12th Isle in 2021. Wennborg brings along experience from her tenure as one half of microsound duo soft tissue, whose 2022 LP 'hi leaves' was a haptic treasure. These approaches mesh remarkably well on their first collaborative full-length, with Duncombe's eerie bio-electronic incantations providing the ideal foil for Wennborg's carbonated hardware processes. It's not completely clear where the human voice ends and the zeroes and ones begin on 'Your Lips, Covering Your Teeth', as rolling cyborg syllables tumble over OS-startup womps and surprisingly svelte outcroppings of glassy, synthetic glitches. The music is surprisingly mannered, a sonic reflection of the cover, where a mouth is pixellated until only colour swatches remain. Duncombe and Wennborg trace the gradual erosion of their voices, leaning into the chaos as their various tools veer off into unique patterns of failure.

What sounds like a far-off, ghosted folk rendition (we're reminded of the Icelandic laments that Rabelais chewed up on 'Spellewauerynsherde') is offset by gnarled, bitcrushed machine faults and pneumatic lip smacks on the brilliant 'Residue', and on 'Brushed My Hair', the duo massage the voice until it sounds like a flute. Assembling stutters and barks and sighs into a celestial chorus alongside time-stretched moans, they create a levitational atmosphere on 'Smell It', freezing the energy from bizarre pitch steps to configure a zonked vocal ensemble.

'Joy, Oh I Missed You’ is an album that, like its source material, constantly morphs, testing the boundaries of its concept repeatedly without bubbling over into conceptual goo. In fact, it's remarkably euphonious, even at its most theoretically abrasive; Duncombe and Wennborg wring out uniquely angelic formations through a process of trial and error that packs a surprising, hefty emotional punch.
