Dusk and Blackdown have been operating on the progressive end of the dubstep spectrum for some time, having released their first material way back in 2005. Desaflex, their second full-length, continues where previous sets left off, offering a deep but surprisingly floor-friendly take on dubstep. Taking influences from a variety of sources - IDM, electronica, garage and UK funky, most obviously - they offer-up a series of well-polished but pleasingly analogue-sounding cuts full of energy and, most importantly, good ideas. At times, their brand of finely tuned bass-tronica sounds like early Black Dog with a dubstep pulse, at others like a futurist outing to Croydon. Throughout, it's a delightful listen.
