"Whereas their past excursions into lo-fi art-rock were all too in thrall to Throbbing Gristle, there's a hitherto unheard melodic nous to the likes of recent single Feet and I Believe in Something Better, the former a skyscraping epic meticulously and irresistibly built up layer by layer, the latter redolent of early-80s Sheffield synthpop. Elsewhere, they boldly meld genres: Fringe Runner is White Lines engulfed in drones; Tastes Good With the Money segues from Gregorian chanting to T Rex glam-boogie, complete with Baxter Dury matter-of-factly warning of "a mushroom cloud for the middle classes". Not everything comes off, however. Kim's Sunsets, despite its provocative angle - empathy for Kim Jong-un, having all that firepower but doomed to never get to use it - fails to transcend its anaesthetised reggae backing. That aside, Serfs Up! feels like a giant leap forward".
