The fourth release on Works The Long Nights sees the return of Karenn, and the most substantial statement of Blawan and Pariah's growing prowess as a duo. Brandishing some six tracks of raw, growling techno spread across two hefty plates of vinyl, Sheworks 004 is as heavy to hold in your hands as the music is uncompromising on your ears. From the off, it's clear Karenn's music has been influenced by the creative constraints afforded by swapping software for hardware, and also Blawan and Pariah's growing relationship with Italian duo The Analogue Cops. The wonderfully grimly titled "Nicotine Window Netting" jostles for favour with its equally well named B Side accompaniment "A Room Full Of Fuck All" - the former dominated by the deranged acid line that jolts around unsettlingly atop the all too dense thud. The latter's drum textures have this strange purring sound and even weirder velveteen, skin crawling sensation and this doesn't even cover the onslaught of tunnelling deranged rave sirens that veer in and out of focus. The vicious "Clean It Up" demonstrates they can manipulate pretty straight forward, heads down yet still blunt techno, while "Lifesbleach" sees them dabbling in tape saturated electro.
