Make a cursory search on the Internet for John T. Gast (presumably not his real name) and it won't be long before the words Hype Williams pop up. Gast worked as a co-producer with Inga Copeland and Dean Blunt on their Black Is Beautiful album and appeared on Blunt's solo effort The Redeemer and with Copeland on UKMerge. It's little surprise, therefore, that Excerpts shares some of the duo's oblique, genre-contorting aesthetic. It's advisable to focus on that, before retracting to view the intrinsic differences which ensure Gast never comes across as a lesser light riding on the coat-tails of more illustrious and talented pals.

The similarities certainly abound: a lot of Excerpts is woozy and layered in ectoplasmic murk that slides into the orbit of hauntology but, like Hype Williams, a sly sense of humour lurking beneath the surface means his music rarely comes across as nostalgic or retro. The lines between past and current influences and reference points, from TV to music to film to video games, are blurred, often quite literally. Gast slathers electronic gunk all over his tracks until their structures become impenetrable, or twists and distorts vocal snippets, in a manner DJ Screw would have baulked at, to the point that actual words are transformed into slabs of inchoate moaning. It's altogether more overtly moody and austere than recent broadcasts from the Hype Williams world, harking back to their untitled debut over Black Is Beautiful's playful aesthetic. Like Untitled, Excerpts is slow-paced (for the most part), grainy and sombre, with crumbling synth textures clustered around skeletal rhythmic shuffles and most human interjections rendered opaque, like ghostly shades mewling in the dark.

While Hype Williams seemed resolutely anchored in a phantomatic Gotham-styled urban setting, the liminal universe on Excerpts is harder to pinpoint. At times, the analogue synths deployed on 'Sedna' and 'White Noise/Dys' definitely evoke the tradition of the Ghost Box stable and Moon Wiring Club more than Hype Williams' dubstep heritage, whilst titles like 'Shanti-ites' and 'Green' have a distinctly pastoral vibe that resurges in the music (the former features a dramatic gloomy choir like something out of the Eyes Wide Shut soundtrack, whilst the latter is dominated by woozy organ drones). A wander through Gast's website throws up all manner of weird artefacts, from photo collages of war and terrorism, to pictures of Northern Irish murals, to abstract imagery seemingly beamed out of the mind of a madman, via YouTube videos of Neil Young's 'Will To Love' (the wooziest love song ever) and martial arts tournaments. I'm sure someone smarter than me could come up with some profound overriding message, but I'm not sure that's even the point. Like early Hype Williams, John T. Gast cultivates a sense of mystery, and even his droll flourishes, like the 45 seconds of vocal deconstruction that is '£' are part of that enigmatic nature.

Where Excerpts really gets interesting, in fact, is when Gast hits the accelerator and plows headlong into dancefloor-oriented material. 'Infection' and 'Congress' form a sharp one-two punch at the start of the album, all infectious repetitive beats, smooth synth lines and elusive vocal loops, in the grand style of Kassem Mosse or Drexciya (or even The Field), but with a few industrial edges thrown in for good measure. He peaks magnificently on 'Claim Your Limbs', on which a dark, brooding atmosphere dominated by crashing snares is undercut by the sheer catchiness of the track's relentless forward motion. To return to that vague world that is hauntology, on these tracks I'm ultimately reminded of the fantastical flights of dance fancy of Umberto's Confrontations album or Pye Corner Audio's Sleep Games.

At times, John T. Gast seems to play the mystery card a bit too intently, but that seems an increasingly common conceit in a lot of electronic music these days. Maybe he'll one day follow Blunt and Copeland into a brighter limelight, but for now he appears to be focusing on defining his own style, one that hurdles a multitude of styles, not always coherently, but with singular verve and commitment.
