Original dubstep soldiers from Croydon N-Type and Cyrus come together on Black Box to drop a double-helping of bassweight. 'Dark Frequency' is a chiller of a tune, spine-tingling strings and ethereal vocals and vibrating mid-range synths drifting mist-like over a riddim track of crusty drums and stomach-churning sub bass movement. 'Conscious' goes yet deeper, the scaly serpentine bassline weaving its way around minimal bongo-laced beats and cold, wintry pads. Support N-Type, Cyrus, Hatcha, Walsh, Youngsta.
