Those with long memories might remember Sex Tags UFO chief DJ Fett Burger's 2012 double A-side collaboration with the mysterious DJ Grillo Weiner, 'Disco Tre'/'Disco Fire' - a deliciously percussive and wayward workout built around choice disco loops and heavy, wayward percussion. 12 years on, the Norwegian pair are back for round two. Fett Burger goes solo on A-side 'Disco Fem', a typically stretched-out fusion of drum machine kicks, densely layered percussion and killer samples from a vintage disco record. It's a genuinely extra, extra-large affair and very, very good. Turn to the flip for 'Disco Sex', a slamming, techno-tempo collaboration that pairs thumping beats and low-slung dub disco bass with mind-mangling synth loops and ambient chords. Like the A-side, it's simply colossal - albeit in a typically eccentric, off-kilter way.
