FACT Magazine recently premiered a new mix from Dusk & Blackdown, two producers at the forefront of dubstep’s constantly evolving landscape. The mix, described by Blackdown as an attempt to “capture a fleeting moment of a scene in transition,” serves up an hour-long offering of UK bass sounds both old and new, with selections from names like Loefah, Benga and El-B. The duo, whose Keysound imprint is responsible for recent releases from Damu and Sully, have put forth a mix that deftly traces dubstep to its roots and back; you can listen to the mix below, and read some of Dusk & Blackdown’s thoughts on the whole thing here.
